These geometric forms can also become structured and organized in a manner that appears to present genuine information to the person experiencing them far beyond the perception of meaningless, although complex, shapes, and colors.
The geometric representations may feel as though they depict specific concepts and neurological processes that exist within the brain in an extremely detailed manner.


'''Geometry''' can be described as the experience of a person’s field of vision being partially or completely encompassed by fast-moving, kaleidoscopic, and indescribably complex geometric patterns, form constants, shapes, fractals, structures and colour.  
Geometry is rarely motionless and is generally extremely fast-moving,<ref name="PapoutsisNikolaou2014" /> and self-changing in regards to its shape and style. During this process, the geometry naturally drifts laterally or radially across the visual field to create overlapping webs of geometric patterns which transition through many distinct states, all of which are visible within a single perceptual frame.


Geometry never stands still at any point and is often extremely fast-changing and self-transforming in terms of its shape and style. During this process, the geometry naturally drifts laterally or radially across the visual field to create overlapping webs of many arising and decaying geometric patterns, all of which are visible within a single perceptual frame.
This experience is often accompanied by other coinciding effects such as [[internal hallucinations]],<ref name="JuszczakSwiergiel2013" /> [[environmental patterning]], and [[drifting]]. It is most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[psychedelic]] compounds such as [[LSD]],<ref name="JuszczakSwiergiel2013" /> [[psilocybin]], and [[mescaline]]. However, it can also occur to a lesser extent under the influence of [[cannabinoid|cannabinoids]], [[entactogens]], and [[dissociative|dissociatives]] such as [[cannabis]],<ref name="BressloffCowan2002" /> [[MDMA]], and [[DXM]].


There are eight different levels of visual geometry, each one increasingly complex and incomprehensible. These are defined and documented below:
Geometry is capable of manifesting itself across known nine different levels of intensity. These tend to depend on the dosage, but can also fluctuate wildly in their intensity due to external triggers such as a person's [[set and setting]]. The individual levels are defined below:


#'''Visual Noise''' – This is the most basic level of geometry and can be experienced in a completely sober state. It can be described as visual noise or static combined with random light and dark red regions that can be seen under the eyelids.
===='''1. Visual noise'''====
#'''Motion and Colour''' – This level is also easily obtainable without [[hallucinogens]] and can be described as the appearance of unstructured regions of fleeting flashes and clouds of colour.
At the lowest level — which may be experienced in a completely sober state — geometry is perceived as visual noise (also known as [[visual snow]], visual static, or [https://en.wikipedia.org/wiki/Eigengrau eigengrau]), combined with stray light and dark red regions that appear under the eyelids.
#'''Partially Defined Geometry''' - At this level complex indescribable shapes and patterns begin to show themselves. However, the patterns can be described as strictly 2-dimensional. They are fine, small, and zoomed out in size with a dark colour palette that limits itself to only a few different shades such as blacks, reds and dark purples. They are displayed in front of both the open and closed-eye visual field across a flat veil of geometry, but are significantly more detailed with the eyes closed or within dark environments.
#'''Fully Defined Geometry''' – This is the level where the detail in which the geometry displays itself becomes profoundly complex but remains strictly 2-Dimensional. At this point the visuals become large in size and extremely intricate in detail with a colour palette that is limitless in its possibilities. They are displayed on both the open and closed-eye visual field across a flat veil of geometry that floats directly in front of the eyes, remaining significantly more detailed with the eyes closed or in dark environments.
#'''3-Dimensional Geometry''' – At level five, the geometry will become fully 3-dimensional in their shape and position across the visual field. This adds a whole new layer of visual complexity and leaves them sprawled out across the surfaces, walls, objects and furniture of ones environment instead of displaying themselves across a basic and flat veil in front of ones visual field.
#'''Partially Overriding Visual Perception''' – At this point the geometry has become so intense, vivid and bright that it has begun to block out and replace the external world. At level six the environment begins to be replaced by geometry, with objects and scenery transforming into sprawling masses of geometry or simply being blocked out and covered by them in a way that partially impairs the use of ones normal vision.
#'''Fully Overriding Visual Perception''' – As the geometry continues to become more intense, vivid and bright it now completely blocks out and replaces the external world as ones sense of normal sight becomes completely impaired. This creates the sensation that one is no longer within the external environment but has broken through into another reality.
#'''Level 8A and Level 8B''' - Once the geometry reaches its eighth and final level, there is not one singular pinnacle of visual geometry but two. It seems that depending on subtle environmental factors and the substance consumed, geometry is capable of forking off into two separate versions of their highest possible level. This means that level eight geometry will have to be separated into two distinct categories of equal intensity. These are known as levels 8A and 8B. Once visual geometry reaches level 8A or 8B, they begin to become structured and organized in a way that presents genuine information to the person experiencing them far beyond the preceding seven levels. This happens through the experience of innately understood geometric representations that feel as though they depict specific concepts and neurological components that exist within the brain. At this point, concepts can be seen as not just embedded within ones closed or open-eye visual field, but simultaneously felt through complex physical and cognitive sensations.


==8A - Exposure to entirety of neurological structure==
===='''2. Motion and color'''====
The experience of level 8A can be described as the feeling feel of being exposed to an infinite mass of geometry comprised entirely of innately readable geometric representations which simultaneously convey every single internally stored concept, memory, and neurological structure stored within the subconscious mind all at once. This results in a profound and overwhelming sensation which is consistently interpreted by people who undergo it as experiencing the entirety of existence, everything, the universe, all that there ever was and all that there ever will be in a single instant.
At this level — which is also obtainable without [[hallucinogen|hallucinogens]] — the effect can be described as the appearance of unstructured regions of sudden flashes and clouds of color. These are typically referred to as phosphenes and can often be experienced in a sober state by rubbing or applying pressure on or near the closed eyes.


This experience is not just perceived as visual data but also physically felt in an incomprehensible level of detail throughout every point across itself as complex and innately understandable tactile sensations which occur across the body. These convey an equal amount of identical information as that which is experienced through one's sense of vision and occurs simultaneously alongside of it.
===='''3. Partially defined geometry'''====
At this level, relatively complex shapes and patterns with a vague structure begin to form. These patterns remain strictly two-dimensional. Geometry at this level is fine, small, and zoomed out in size with a dark color palette that typically limits itself to only a few different shades, such as blacks, reds, and dark purples. They are displayed in front of both the open and closed eye visual fields across a flat veil of geometry. However, they are significantly more detailed with the eyes closed or within dark environments.


At the lower side of level 8A, this effect is something that fluctuates wildly and remains neither constant nor consistent in its intensity. Instead it is temporarily triggered by the experience of a concept. For example, if somebody were to say the word “internet” to a person who is currently undergoing this state, they would see the mind's concept of the internet immediately manifested in a geometric form amidst the very centre of their visual field. This form quickly branches out from itself in a fashion similar to an ineffable spider diagram. It expands to envelop the concepts which one associates with the internet and then branches out again to include the concepts one associates with those before repeating the process of branching out further to represent the concepts associated with these ad infinitum. Within 2 - 3 seconds, this exponentially expands within a sudden perceptual flash to include every single internally stored concept within the subconscious memory banks of one's mind simultaneously.
===='''4. Fully defined geometry'''====
At this level, the detail in which the geometry displays itself becomes profoundly complex and fully structured, but still remains strictly two-dimensional. At this point, the geometry becomes larger in size and extremely intricate in detail with a color palette that is nearly limitless in its possibilities. They are displayed on both the open and closed eye visual field across a flat veil of geometry that floats directly before a person's eyes, remaining significantly more detailed with the eyes closed or in dark environments.


Once this occurs, the sensory overload temporarily disconnects the tripper from their external environment and results in simultaneous [[Cognitive effects: Ego suppression, loss and death|ego death]] before re-stacking them back into the room, until something triggers the process again (usually immediately). The effect snaps trippers in and out of the room repeatedly and the process is triggered continuously. It's worth noting however that at this level it can to a certain extent be held at bay through continuous physical movement. This is because movement stops the process from branching out into everything by not giving the effect the time it needs to lock onto a concept.
===='''5. 3-Dimensional geometry'''====
At this level, the geometry has become fully three-dimensional in its shape and position across the visual field. This adds a new layer of visual complexity and leaves the geometry sprawled out across the surfaces and objects of a person's environment instead of merely displaying themselves across a basic and flat veil in front of one's visual field.
As dosage is increased, the process becomes easier and easier to trigger whilst extending in its length and duration. This eventually results in a stable state of complete disconnection from the external environment alongside of sustained [[Cognitive effects: Ego suppression, loss and death|ego death]] and a lasting sense of experiencing the entirety of one's neurological structure.


==8B - Exposure to inner mechanics of human consciousness==
===='''6. Partially overriding visual perception'''====
The experience of level 8B can be described as the feeling of being exposed to a mass of geometry comprised entirely of innately readable geometric representations which feel as if they convey the organization, structure, framework and inner mechanics of the underlying programming behind all conscious and subconscious neurological processes. This effect is consistently interpreted by those who undergo the experience as perceiving the inner workings of either the universe, consciousness or reality.  
At this level, the geometry has become so intense, vivid, and bright that it has begun to block out and replace the external world. The visual perception of a person's environment begins to be replaced by geometry, with objects and scenery either transforming into complex geometric structures or simply being blocked out and covered by them. This occurs in a manner that drastically impairs the use of a person's normal vision. From this level of geometry onwards it is even possible to view geometry which is perceived to be four-dimensional or created from new, ineffable, non-euclidean, or nonsensical geometrical principles, although this is more common at higher levels.


At the lower end of level 8B geometry, the experience manifests itself as becoming and being able to physically feel and visually perceive the organization and structure of the underlying programming behind ones current conscious thought stream. This is presented to trippers in the form of a fast-moving and infinite web or network that contains innately understood and thought-stream-relevant geometric representations of specific and abstract concepts embedded into each and every one of the connecting points across itself. The experience of these innately readable geometric representations consistently triggers one to visualize and physically feel the concept perfectly through highly detailed [[Cognitive effects: Conceptual thinking|conceptual thinking]]. The ever-shifting network follows the pace and rhythm of ones internal dialogue perfectly. This creates and manifests new connections in a way that is both physically felt through a powerful sensation, and seen embedded within your visual field every time any piece of new insight or knowledge is gained.
===='''7. Fully overriding visual perception'''====
At this level, the geometry continues to become more intense, vivid, and bright as it begins to completely block out or replace the external world and a person's sense of normal sight become completely impaired. This creates the perception that one is no longer within the external environment, but has "broken through" into another reality of extremely complex and otherworldly geometric forms.


At the higher end of level 8B geometry, the effect retains its lower levels (described above) but expands itself to include the experience of visually perceiving through innately readable geometric representations, the architecture of the subconscious mind and all neurological processes outside of our internal narrative which build up the architecture.  
===='''Level 8A and level 8B'''====
At the highest level, geometry is capable of forking off into two separate levels of equal intensity known as level 8A and 8B. Environmental factors, a person's state of mind, and the substance consumed may determine which level a person experiences.


The experience of level 8B as a whole is not just perceived as visual data but also physically felt in an incomprehensible level of detail throughout every point across itself as complex and innately understandable tactile sensations which occur across the body. These convey an equal amount of identical information as that which is experienced through ones sense of vision and occurs simultaneously along side of it.
Once visual geometry reaches level 8A or 8B it begins to become structured and organized in a way that appears to present genuine information to the person experiencing it far beyond the preceding seven levels of relatively meaningless, although complex, shapes and colours. This occurs through the perception of innately understood geometric forms that feel as if they depict specific concepts and neurological processes that exist within the brain. Although this is also possible to a much lesser extent at lower levels it does not occur as consistently, and the intensity of it at levels 8A and 8B is significantly higher. At this point concepts can be seen as not just embedded within a person's closed or open eye visual field, but can also be simultaneously felt through indescribably complex physical and cognitive sensations.


This state is capable of bestowing specific pieces of information onto trippers regarding the nature of reality and human consciousness through the simple experience of them. These specific pieces of information are always immediately felt and understood to be a profound unveiling of an undeniable truth at the time, but afterwards they are often found to be ineffable due to the limitations of human English or simply nonsensical due to the disorientation of the accompanying cognitive effects.
It is worth noting that there are particular attributes of psychedelic substances which tend to result in a higher likelihood of level 8A over 8B and vice versa. Psychedelics which are physically [[stimulation|stimulating]] and contain low amounts of [[hallucinatory states|hallucinatory content]] typically result in level 8A. For example, hallucinogens which tend towards causing level 8A include [[LSD]], [[2C-B]], and [[4-HO-MET]]. In contrast, psychedelics which lead to level 8B are typically [[sedation|sedating]] in physical effects and contain high amounts of hallucinatory content. For example, hallucinogens which tend towards causing level 8B include [[psilocybin]], [[LSA]], [[DMT]], and [[2C-T-7]].


Occasionally, however, genuine lessons or coherent messages are innately interpreted through the experience of becoming and descending down into the subconscious faculties of the brain. It’s extremely important to note, however, that the scientific validity of these lessons are very uncertain and should never be immediately accepted as fact without an extremely thorough and sober analysis.

==Variations==
====Shipibo textiles====
*'''Intricate vs. Simplistic''' – Geometry can either present itself as incomprehensibly intricate and complex in its appearance or simplistic and comprehensible even at higher dosages.
<center>
*'''Algorithmic vs. Abstract''' – Geometry can either appear to follow mathematical rules and logically consistent forms in its shape, often resulting in high amounts of fractals and semi predictable shapes. In contrast to this, geometry can also be completely abstract or random in its appearance in a way that contains infinite amounts of completely unpredictable variety.
{{Gallery|[[Effect::Geometry]][[Category:Textile]][[Category:Replication]]}}
*'''Organic vs. Synthetic''' - Geometry can either feel organic and natural in its visual style or it can synthetic and digital.
</center>
*'''Structured vs. Unstructured''' – Geometry can either present itself as completely unorganized and unstructured or they can form and condense into an infinite variety of 3-Dimensional mechanistic and ever-shifting structures which are comprised out of and based upon condensed geometry.
*'''Dimly lit vs. Brightly lit''' - Geometry can either present itself as extremely dark and hard to make out from its background or in contrast it can be brightly lit and extremely easy to distinguish from its background.
*'''Multicoloured vs. Monotone''' – The colour scheme that geometry follows can range from extremely varied and-multi coloured in style to consisting of little if any colour variety such as blues and greys or purples and blacks
*'''Flat shading vs. Glossy shading''' – This is separate from the variety of colour contained within geometry. Colours can either be flat, bright and simplistic or glossy with depth, high lights and shading.
*'''Sharp edges vs. Soft edges''' – Geometry can have sharp edges which are extremely well-defined around their perimeter (sometimes with thick black outlines around their edges). In contrast to this, they can also be soft and blurred around their edges, merging seamlessly into each other in a way that does not affect their intricacy.
*'''Large vs. Small''' – In terms of their size, geometry can be extremely large and zoomed in or fine and zoomed out in a way that does not affect their level of intricacy.
*'''Fast vs. Slow''' – In terms of its speed, geometry can shift and morph so fast into themselves that the amount of information presented to the tripper in extremely short periods of time becomes incomprehensible to process. In contrast to this, they can move slowly and comprehensibly, swirling and shifting into themselves to present ever changing geometric forms that can be observed in a much higher level of detail.
*'''Smooth vs. Jittery''' - In terms of its motion, geometry can be smooth in its motion with a high frame rate or it can be jittery in its motion with lag and a low frame rate.
*'''Round corners vs. Angular corners''' – Geometry can either have mostly rounded and circular corners or mostly sharp corners with pointed and angular geometry.
*'''Immersive vs. Unimmersive''' – Geometry can be manifested in front of ones face on a field of vision that feels separate as if it was being presented on some sort of television screen without a distinct sense of size or distance attributed to them. In contrast, geometry can feel as if one is completely immersed in and surrounded by them with a distinct sense of attributed size and distance.
*'''Consistent vs. Progressive''' - Geometry can be manifested as consistent and steady in its intensity, complexity and visibility regardless of disturbances within the external environment. In contrast however it can manifest as progressive in its intensity which means that disturbances and sensory input such as bright lights, loud noises and distractions within the external environment will prevent or cut off the intensity, complexity and visibility from building up to its limit whilst darkness will cause it to progressively rise in complexity.
*'''[[Visual effects: Geometry#8A_-_Exposure_to_entirety_of_neurological_structure|Level 8A]] vs. [[Visual_effects: Geometry#8B_-_Exposure_to_inner_mechanics_of_human_consciousness|Level 8B]]''' – At its eigth and highest level of experience, geometry is capable of branching off into two different directions of equal intensity. The first of these is [[Visual effects: Geometry#8A_-_Exposure_to_entirety_of_neurological_structure|Level 8A – exposure to entirety of neurological structure]] and the second of these is [[Visual_effects: Geometry#8B_-_Exposure_to_inner_mechanics_of_human_consciousness|Level 8B – exposure to the inner mechanics of human consciousness]].

===Variations===
The specific differences between each potential style of geometry can be broken down into the following variations:
 
*'''Intricate vs. simplistic''' - Geometry can either present itself as incomprehensibly intricate and complex in its appearance or simplistic, basic and comprehensible even at higher doses. For example, the geometry associated with [[dissociative]]s tends to be consistently overly simplistic in form while most psychedelics are significantly more intricate.
*'''Algorithmic vs. abstract''' - Geometry can either appear to follow mathematical rules and logically consistent forms in its design (which often results in high amounts of fractals and semi-predictable shapes). In contrast to this, however, geometry can also be completely abstract or random in its appearance in a way that contains an infinite amount of completely unpredictable variety.
*'''Organic vs. synthetic''' - Geometry can either feel subjectively organic and natural in its visual style, or it can feel synthetic and digital.
*'''Unstructured vs. structured''' - Geometry can either present itself as completely disorganized and unstructured or it can form and condense into a variety of 3-dimensional mechanical and ever-shifting structures which are comprised out of and based upon condensed geometry.
*'''Dimly lit vs. brightly lit''' - Geometry can either present itself as extremely dark and hard to make out from its background or, in contrast, it can be brightly lit and extremely easy to distinguish from its background. For example, the geometry associated with [[dissociative]]s tends to be consistently darker in appearance while most psychedelics are significantly brighter.
*'''Multicolored vs. monotone''' - The color scheme that geometry follows can range from extremely varied and multicolored in style to consisting of little (if any) color variety such as grays, purples and blacks
*'''Flat shading vs. glossy shading''' - The shading of geometry can either be flat, bright and simplistic or glossy with depth, gradients, highlights, and shading.
*'''Sharp edges vs. soft edges''' - Geometry can have sharp edges which are extremely well-defined around its perimeter (sometimes with thick black outlines around its edges). In contrast to this, they can also be soft and blurred around the edges, merging seamlessly into each other in a manner which does not affect its intricacy.
*'''Large vs. small''' - Regarding its size, geometry can be extremely large and zoomed in or fine and zoomed out in a way that does not affect its level of intricacy.
*'''Fast vs. slow''' - In terms of its speed, geometry can shift and morph so fast into itself that the amount of information presented to the tripper in extremely short periods of time becomes incomprehensible to process. In contrast to this, they can move slowly and comprehensibly, swirling and shifting into themselves to present ever-changing geometric forms that can be observed at a much higher level of detail.
*'''Smooth vs. jittery''' - In terms of its motion, geometry can move smoothly with a high frame rate, or it can be jittery in its motion with lag and a low frame rate.
*'''Round corners vs. angular corners''' - Geometry can either have mostly rounded and circular corners or mostly sharp corners with sharp and angular geometry.
*'''Non-immersive vs. immersive''' - Geometry can be manifested in front of one's face in a manner which feels separate and as if it was being presented on some screen without a distinct sense of size or distance attributed to it. In contrast, geometry can feel as if one is completely immersed in and surrounded by it with a distinct sense of attributed size and distance.
*'''Consistent vs. progressive''' - Geometry can be manifested as consistent and steady in its intensity, complexity and visibility regardless of disturbances within the external environment. In contrast, however, it can manifest as progressive in its intensity which means that disturbances and sensory input such as bright lights, loud noises and distractions within the external environment will prevent or cut off the intensity, complexity and visibility from building up to its limit whilst darkness will cause it to steadily rise in complexity.
*'''[[8A Geometry|Level 8A]] vs. [[8B Geometry|level 8B]]''' - At its eighth and highest level of experience, geometry is capable of branching off into two different directions of equal intensity. The first of these is [[8A Geometry|Level 8A – exposure to semantic concept network]] and the second of these is [[8B Geometry|Level 8B – exposure to the internal mechanics of consciousness]]. </onlyinclude>
