Abstract: Severe stress may precipitate transient, complex hallucinations, which the subject recognises as arising from his or her imagination.'819 Dissociative (conversion) phenomena may account both for these pseudohallucinations and for many spiritual and paranormal phenomena.820A dissociative mech- anism may also underlie memory flashbacks (which may be experienced as real2) in post-traumatic stress disorder.22Dissociative experiences may even be normal.8Isolated hallucinations may be common and normal per- ceptual errors and no more indicative of psychiatric illness than isolated illusions.But, whether we describe visions and voices as psychotic, dissociative, hypnagogic, or normal, uncertainties remain about their underlying psychophysiology and the relations between these seemingly very different states of mind.
