"The relationship between religion and schizophrenia is of particular interest to psychologists because of the similarities between religious experiences and psychotic episodes; religious experiences often involve auditory and/or visual hallucinations, and those with schizophrenia commonly report similar hallucinations, along with a variety of delusions and faulty beliefs. A common report from those with schizophrenia is some type of a religious delusion - that is, they believe they are divine beings, God is talking to them, they are possessed by demons, etc.[5][6][7] In a study of patients with schizophrenia that had been previously admitted to a hospital, 24% had religious delusions.[8] This has led some researchers to question whether schizophrenia leads an individual to become more religious, or if intense religiosity leads to schizophrenia.[9]"
