Hallucination

From Openwaterpedia

noun - A hallucination is a perception in the absence of a stimulus which has qualities of real perception. Hallucinations are vivid, substantial, and located in external objective space including out in an open body of water, especially by channel swimmers and marathon swimmers who have been swimming for hours at a time.

Hallucinations are distinguished from the related phenomena of dreaming, which does not involve wakefulness; illusion, which involves distorted or misinterpreted real perception; imagery, which does not mimic real perception and is under voluntary control; and pseudohallucination, which does not mimic real perception, but is not under voluntary control.

Hallucinations can occur in any sensory modality — visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive.
