Autoscopy is a visual experience in which a person sees an image of themselves in external space from within their own body. A review of 53 published cases since 1935 plus three personally observed patients found 38 men and 18 women, average age 39.5 years. Neurological illness, most often epilepsy, occurred in 59% of subjects, and psychiatric disorder in 59%, commonly delirium, depression, or psychosis. Speaking images were associated with younger age, male sex, psychotic illness, longer image duration, and hypnagogic/hypnopompic experiences. Autoscopy may result from a convergence of gender, personality, neurological and psychiatric disease, exhaustion, and dissociation overriding normal inhibition of temporal lobe activity.
