Ordinary experimental hypnotic and posthypnotic suggestions of hallucinations are well known.

The recurrence of certain designs and patterns in human hallucinatory experience is probably related to structural aspects of the visual system. Alternatively, the hallucinations may take the form of unique visual imagery for example, the yantra is a visual hallucination of a coloured, geometrical image that appears at a level of trance of the sort experienced by practitioners of Yoga.

The hallucinations may be of the type in which the person perceives his “inner self” to leave his body to view himself ( autoscopic hallucination) or to be transported to new surroundings. Such individuals can accomplish an astonishing withdrawal from the environment by prolonged intense concentration (e.g., by gazing at some object). The mystic achieves hallucinations by gaining control of his own dissociative mechanisms perhaps this is a form of self-hypnosis. (The disorganizing effect of sleep deprivation has been exploited in extorting confessions from prisoners.) Observations suggest that fleeting hallucinations typically begin after two or three days without sleep, and that after 100 to 200 sleepless hours a progressive personality disorganization will develop, marked by periods of hallucinosis or, in some cases, by the reappearance of a previously existing psychiatric disorder. Hallucinations probably will occur in anyone if wakefulness is sufficiently prolonged anxiety is likely to hasten or to enhance hallucinatory production.

Progressive sleep loss appears to decrease one’s capacity for integrating realistic perceptions of the external environment. If stimuli are markedly reduced and the level of arousal is high, the hallucinations can be especially vivid and emotionally charged. A slight amount of stimulation directed toward the senses may further increase the likelihood of hallucination. A person who remains alert during a period of sensory deprivation is likely to experience vivid fantasies and, perhaps, hallucinations. When people are kept in isolation (sensory deprivation), information input via the senses (such as hearing and sight) is reduced.
