The term psychotic-like hallucination is indebted to the medical Latin term * psychosis, which in turn stems from the Greek noun psuchosis (the giving of life, the process of animating). It is used more or less interchangeably with terms such as *pseudohallucination, *quasi-hallucination, and * dissociative hallucination. All these terms are used to express the observation that the phenomenon in question is reminiscent of a * hallucination proper, but that it lacks one or more of the latter's formal characteristics. The term psychotic-like hallucination is used in opposition to terms such as hallucination proper, *true hallucination, "veridical hallucination, and "psychotic hallucination.
