The common definition found in a dictionary is something like this: Is this definition sufficient? Can one define the "boudaries of reality'? Is the term Psychosis more one of utility than describer or explanation? I would think that most persons on the planet are in some way psychotic by this definition at some stages in their lives, but what gives this word so much power? Does having a halucination automatically attract the label of psychosis? Could having a dream be considered as a psychotic episode? How would we determine that a person is psychotic? Is it just because of his beliefs or is it because of his actions based on those belief? Many many questions seem to come to mind about this topic and would any one care to help in the understanding of it?
