''' | An '''internal hallucination''' is defined as the perception of a visual hallucination that exclusively occurs within an imagined environment which can typically only be viewed with closed eyes,<ref name="Siegel1985">{{cite journal|last1=Siegel|first1=Ronald K.|title=LSD Hallucinations: From Ergot to Electric Kool-Aid|journal=Journal of Psychoactive Drugs|volume=17|issue=4|year=1985|pages=247–256|issn=0279-1072|doi=10.1080/02791072.1985.10524329}}</ref><ref name="KometerSchmidt2013">{{cite journal|last1=Kometer|first1=M.|last2=Schmidt|first2=A.|last3=Jancke|first3=L.|last4=Vollenweider|first4=F.

At lower levels, internal hallucinations begin with imagery on the back of a person's eyelids which do not take up the entirety of one's visual field and are distinct from their background. These can be described as spontaneous moving or still images of scenes, concepts, places, and anything one could imagine. The imagery is manifested in varying levels of realism, ranging from ill-defined and cartoon-like in nature to wholly realistic. They rarely hold their form for more than a few seconds before fading or shifting into another image. It is worth noting that this level of intensity occurs in a highly similar manner to that of [[hypnagogia]], the state between sleep and wakefulness. | At lower levels, internal hallucinations begin with imagery on the back of a person's eyelids which do not take up the entirety of one's visual field and are distinct from their background.

It is worth noting that the content, style, and general behaviour of an internal hallucination is often largely dependent on the emotional state of the person experiencing it. For example, a person who is emotionally stable and generally happy will usually be more prone to experiencing neutral, interesting, or positive hallucinations. In contrast, however, a person who is emotionally unstable and generally unhappy will usually be more prone to experiencing sinister, fear-inducing, and negative hallucinations. | |||
Internal hallucinations are often accompanied by other coinciding effects such as [[geometry]], [[external hallucinations]] and [[delusions]]. They are most commonly induced under the influence of [[dosage#heavy|heavy]] [[dosage|dosages]] of [[hallucinogen|hallucinogenic]] compounds, such as [[psychedelic|psychedelics]], [[dissociative|dissociatives]], and [[deliriant|deliriants]]. However, they can also occur under the influence of [[stimulant psychosis]], [[sleep deprivation]], and during [[dreams]]. | Internal hallucinations are often accompanied by other coinciding effects such as [[geometry]], [[external hallucinations]] and [[delusions]].

===Variations=== | ===Variations=== | ||
The specific differences between each potential style of internal hallucination can be broken down into the following variations: | |||
*'''Lucid vs. Delirious''' - Hallucinatory states can maintain a consistent level of awareness throughout them regarding the fact that none of these events are actually happening and that the current situation is simply a result of drug-induced hallucination. In contrast to this, hallucinations can also become completely believable, no matter how nonsensical they may be, in the same way, that one does not have any problem accepting "absurd" and non-linear plots within ones [[dreams]]. | *'''Lucid vs. Delirious''' - Hallucinatory states can maintain a consistent level of awareness throughout them regarding the fact that none of these events are actually happening and that the current situation is simply a result of drug-induced hallucination.

*'''Interactive vs. Fixed''' – Hallucinatory states can either present themselves as completely separate in a manner, that is similar to watching a video play out in front of one's field of vision, or they can be completely interactive. For example, conversing with [[autonomous entities]] or interacting with imagined objects in a fashion similar to [[lucid dreaming]] is entirely possible. | *'''Interactive vs. Fixed''' – Hallucinatory states can either present themselves as completely separate in a manner, that is similar to watching a video play out in front of one's field of vision, or they can be completely interactive.

In contrast, autonomous hallucinations are completely spontaneous in their subject matter and entirely uncontrollable. | ||
*'''Geometry-based vs. Solid''' – Hallucinations can be comprised of condensed [[psychedelic]] [[geometry]] or they can appear to be made from realistic materials. | *'''Geometry-based vs. Solid''' – Hallucinations can be comprised of condensed [[psychedelic]] [[geometry]] or they can appear to be made from realistic materials. | ||
