Hallucination is the most common symptom, among other psychopathological manifestations of schizophrenia, bipolar disorder and exogenous-organic mental pathology; delusions are rare, and obsessive states do not go beyond obsessions. Aggravating symptoms testify in favor of psychosis: stupor, stupor, disorientation in time and place, “empty” minutes and, least of all, delusional statements.
Miguel Pazote describes "teleological hallucinations" (hallucinations based on causes present in reality, which perceives the body and sends it back), in which objects relate to the feeling of hunger or consumption. Miguel Pasot analyzed 18 "teleological" hallucinations in the monograph - all the cases listed in the medical literature since Francis Bacon reported a case of a man experiencing a very varied menu through a hole in the ground in Cornwall in 1647. Montague describes "teleological" hallucinations as caused by vertigo in a depressed (suicidal) person who is now haunted by unpleasant images of people from his past. Terry Lynn is a child with a classic history of severe emotional trauma and depression, experiencing many "teleological hallucinations", demonstrating an inability to distinguish between the real and the imaginary.
