Autoscopy

A term dating from the Mesmeric age and denoting the power of somnambules to see their own organs and give a description of their state. The word was coined by neurologist Charles Féré. He applied it to the vision his patients saw of their double in a morbid state. This is external autoscopy, as contrasted by Baron du Potet to internal autoscopy: self-diagnosis in a trance. Dr. Sollier wrote a monograph, Les Phénomènes d'autoscopie (Paris, 1903), on the subject.

autoscopy (aw-tos-kŏpi) n. the experience of seeing one's whole body as though from a vantage point some distance away. It can be a symptom in epilepsy. See also out-of-the-body experience.
