'''External hallucinations''' can be described as the experience of perceiving imagined visual concepts and occurrences which display themselves seamlessly into the external environment as if they were actually happening. They can be broken down into 4 basic levels: | '''External hallucinations''' can be described as the experience of perceiving imagined visual concepts and occurrences which display themselves seamlessly into the external environment as if they were actually happening.

#'''Vaguely defined hallucinations''' - At this level the hallucinations are visible within one's direct line of sight but are not fully defined in their appearance. This means that although visible, they do not look completely detailed and are often blurry or semi-translucent with little if any colour. | #'''Vaguely defined hallucinations''' - At this level the hallucinations are visible within one's direct line of sight but are not fully defined in their appearance.

#'''Partially defined hallucinations''' - At this level the hallucinations increase into a high enough amount of detail and vividness to extend beyond transparent, colourless or blurry manifestations. However, they still remain unconvincing and do not quite live up to the detail of completely realistic and convincing hallucinations. | #'''Partially defined hallucinations''' - At this level the hallucinations increase into a high enough amount of detail and vividness to extend beyond transparent, colourless or blurry manifestations.

There are certain factors that directly alter both the likelihood of external hallucinations manifesting themselves and the level of detail which they are rendered in. The more unfamiliar with the external environment one is, the more this effect will be likely to manifest itself. Cluttered areas also tend to produce more external hallucinations. As far as lighting goes, either a dark or dim room is optimum. Darkness produces much more hallucinations but the light present in a dim room will result in less (though more detailed) hallucinations. | There are certain factors that directly alter both the likelihood of external hallucinations manifesting themselves and the level of detail which they are rendered in.

*'''New experiences vs. Memory replays''' – In terms of their subject matter, hallucinations can either be entirely new experiences or they can follow themes of normal every day concepts and a replaying of specific memories. | *'''New experiences vs. Memory replays''' – In terms of their subject matter, hallucinations can either be entirely new experiences or they can follow themes of normal every day concepts and a replaying of specific memories. | ||
*'''Controllable vs. Autonomous''' – Imagery and hallucinations can be partially to completely controllable. This can be described as the content of their appearance always seeming to perfectly follow and fit the general topic and subject matter of one's current thought stream with varying levels of partial to absolute control. In contrast, autonomous hallucinations are completely spontaneous in their subject matter and entirely uncontrollable. | *'''Controllable vs. Autonomous''' – Imagery and hallucinations can be partially to completely controllable.
