Psychotic manifestations in adolescence can take on a defensive aspect when dealing with psychotic illness, a breakdown (Laufer, M. and M. E.). Fanny presented delusive and hallucinatory activity and her symptoms disappeared after two years of therapy. Psychotherapeutic technique must follow a common thread: the conviction that the delirious and the hallucinatory belong to the internal world of the patient and form part of her narrative about herself; the associative thread of the session makes it possible to suggest that the patient invite psychotic elements into her psychic space or world, thereby putting them into the “world,” which is an identity created by the psychotic person.
