Hallucination

Science / Psychiatry / Hallucination: false sensory perception in the absence of a real external stimulus. It is perceived as being located in objective space and as having the same realistic qualities as normal perceptions. It is not subject to conscious manipulation and only indicates a psychotic disturbance when there is also impaired reality testing. Hallucinations may be seen, heard, touched, tasted, or smelled by the ill individual. The term hallucination is not ordinarily applied to the false perceptions that occur during dreaming, while falling asleep (hypnagogic), or when awakening (hypnopompic). Transient hallucinatory experiences may occur in people without a mental disorder.
