Autoscopy is the experience in which an individual perceives the surrounding environment from a different perspective, from a position outside of his or her own body.[1] Autoscopy comes from the ancient Greek αὐτός ("self") and σκοπός ("watcher").
Autoscopy has intrigued humankind from time immemorial and is abundant in the folklore, mythology, and spiritual narratives of most ancient and modern societies. Cases of autoscopy are commonly encountered in modern psychiatric practice.[2] According to neurological research, autoscopic experiences are hallucinations.[1][3]

Factors
Experiences - are characterized by the presence of the following three factors:
- disembodiment, an apparent location of the self outside one's body;
- impression of seeing the world from an elevated and distanced visuo-spatial perspective or extracorporeal, but egocentric visuo-spatial perspective;
- impression of seeing one's own body from this perspective (autoscopy).
Laboratory of Cognitive Neuroscience, École Polytechnique Fédérale de Lausanne, Lausanne, and Department of Neurology, University Hospital, Geneva, Switzerland, have reviewed some of the classical precipitating factors of autoscopy. These are sleep, drug abuse, and general anesthesia as well as neurobiology. They have compared them with recent findings on neurological and neurocognitive mechanisms of the autoscopy. The reviewed data suggest that autoscopic experiences are due to functional disintegration of lower-level multisensory processing and abnormal higher-level self-processing at the temporoparietal junction.[1][4]
Related disorders
Heautoscopy is a term used in psychiatry and neurology for the reduplicative hallucination of "seeing one's own body at a distance".[5] It can occur as a symptom in schizophrenia[6] and epilepsy. Heautoscopy is considered a possible explanation for doppelgänger phenomena.[7]
The term polyopic heutoscopy refers to cases where more than one double is perceived. In 2006, Peter Brugger and his colleagues described the case of a man who experienced five doubles resulting from a tumor in the insular region of his left temporal lobe.[8]
Another related autoscopy disorder is known as negative autoscopy (or negative heautoscopy) a psychological phenomenon in which the sufferer does not see his or her reflection when looking in a mirror. Although the sufferer's image may be seen by others, he or she claims not to see it.[1]
