A term used in parapsychology to denote a hallucination that has no bearing on actual events in the external world. The term falsidical hallucination is used in opposition to the term *veridical hallucination. The latter term has various connotations, but in the present situation it is used to denote a hallucination that has a bearing on actual people, objects, or situations from which the * hallucinator is separated in place and/or time. One could say that according to the biomedical tradition, all hallucinations belong to the class of - what parapsychologists would call - fal-sidical hallucinations.
