BACKGROUND: Sleep dysfunction is extremely common in @entity1 with @entity161 . Recent research indicates that @entity22 may contribute to @entity716 experiences such as delusions and @entity1833 . OBJECTIVES: The review aims to evaluate the evidence for a relationship between @entity22 and individual @entity716 experiences, make links between the theoretical understanding of each, and highlight areas for future research. METHOD: A systematic search was conducted to identify studies investigating sleep and @entity716 experiences across clinical and non-clinical populations. RESULTS: 66 papers were identified. This literature robustly supports the co-occurrence of @entity22 and @entity716 experiences, particularly @entity22 with @entity10963 . Sleep dysfunction predicting subsequent @entity716 experiences receives support from epidemiological surveys, research on the transition to @entity716 , and relapse studies. There is also evidence that reducing sleep elicits @entity716 experiences in non-clinical individuals, and that improving sleep in individuals with @entity716 may lessen @entity716 experiences. @entity148 and @entity308 consistently arise as (partial) mediators of the sleep and @entity716 relationship. CONCLUSION: Studies are needed that: determine the types of @entity22 linked to individual @entity716 experiences; establish a causal connection between sleep and @entity716 experiences; and assess treatments for @entity22 in @entity1 with non-affective @entity914 such as @entity161 .
