- specular hallucination
- The term specular hallucination is indebted to the Latin noun speglum, which means mirror. It was introduced in or shortly before 1891 by the French physician and mesmerist Charles Féré (1852-1907) to denote an *autoscopic hallucination depicting the affected individual's exact mirror image, including his or her movements and gestures. As Féré wrote, "It has been proved that the hallucination can consist of an exact animated reproduction like one sees in a mirror; therefore, the name specular hallucination [hallucination spéculaire] is the one that strikes me as the most appropriate." Specular hallucinations are sometimes classified as * reduplicative hallucinations.ReferencesBrugger, P., Regard, M., Landis, Th. (1997).
