A term introduced in or shortly before 1903 by the French physician and psychologist Paul Auguste Sollier (1861-1933) to denote a type of "autoscopy (i.e. 'seeing one self) characterized by a "visual or "compound hallucination depicting the body s exterior features. Sollier uses the term external autoscopy in opposition to "internal autoscopy (i.e. a visual hallucination displaying the body's internal organs). He classifies both external and internal " autoscopic hallucinations as " coenesthetic hallucinations.
