The term psychogenic hallucination is indebted to the medical Latin term * psychosis, which in turn comes from the Greek noun psuchosis (the giving of life, the process of animating). It translates loosely as a 'hallucination created by the psyche'. The term psychogenic hallucination tends to be used quite loosely to denote a hallucination which is attributable to the brain's higher integrative centres (or the psyche, in a dualist reading). It derives from the psychological literature and tends to be used in the context of a psychodynamic interpretation of the percepts in question. Some examples of hallucinations traditionally classified as psychogenic are the *conversive hallucination, the * scenic hallucination, *hallucinatory confusion, *psychogenic pain, * hallucinated pain, and * algopsychalia. In clinical practice the term psychogenic hallucination is sometimes used as more or less synonymous with * pseudohallucination.
