Psychosis - Psychotic experience: Encyclopedia II - Psychosis - Psychotic experience

A psychotic episode can be significantly coloured by mood. For example, people experiencing a psychotic episode in the context of depression may experience persecutory or self-blaming delusions or hallucinations, while people experiencing a psychotic episode in the context of mania may form grandiose delusions or have an experience of deep religious significance. Although usually distressing and regarded as an illness process, some people who experience psychosis find beneficial aspects and value the experience or revelations that stem from it.
