Auditory hallucinations are typical of psychoses: third-person hallucinations (i.e. voices talking about the patient) and hearing one's thoughts spoken aloud ("gedankenlautwerden" or "écho de la pensée") are among the Schneiderian first rank symptoms indicative of schizophrenia, whereas second-person hallucinations (voices talking to the patient) threatening or insulting or telling them to commit suicide, may be a feature of psychotic depression or schizophrenia. Visual hallucinations are generally suggestive of organic conditions such as epilepsy, drug intoxication or drug withdrawal. Many of the visual effects of hallucinogenic drugs are more correctly described as visual illusions or visual pseudohallucinations, as they are distortions of sensory experiences, and are not experienced as existing in objective reality. Auditory pseudohallucinations are suggestive of dissociative disorders. Déjà vu, derealization and depersonalization are associated with temporal lobe epilepsy and dissociative disorders.
