Freud discriminates between loss of reality in neurosis and its loss in psychosis. In neurosis, a flight occurs, whereas in psychosis a remodeling of the facts takes place. The individual may use methods of denial suggesting psychosis, but on the other hand some types of disavowal that occur in childhood are considered normal. Psychoanalysts should be very clear about the meaning of disavowal; it is a self-deception in the face of an accurate perception. Disavowal has a defensive aspect, and if it fails, there may be much adaptation in functioning. Anna Freud points out that if the disavowal persists from childhood into adulthood, it really constitutes psychosis. The use of fantasy is an important aspect of healthy development and growth; for example, fetishism may serve the purpose of defending the individual from psychosis.
