AUTOSCOPY FOR DUMMIES
"Autoscopy was defined by Critchley (1950) as 'delusional dislocation of the body image into the visual sphere' and by Lukianowicz (1958) as 'a complex psychosensorial hallucinatory perception of one's own body image projected into the external visual space'. Both these imply that the self remains associated with the physical body and that a duplicate body is seen at a distance."
