Shorter sleep time and negative dream valence predict paranoid symptoms, while feeling less rested and recalling dreams predict hallucinatory experiences. In people with elevated psychosis proneness, these sleep-related effects on hallucinations are stronger. The relationship between poor sleep and paranoia is bidirectional, but poor sleep only predicts hallucinations, not the reverse. The findings highlight sleep disturbance as a contributor to psychotic experiences and suggest that improving sleep could help prevent such symptoms.
