The present review aimed to 1) identify what sleep disturbances co-occur alongside psychotic-like, dissociative and hypomanic experiences; 2) assess the strength of potential associations between the severity of sleep disturbances and of the experiences studied; and 3) appraise evidence for a causal link. MedLine and PsycInfo were searched and 44 studies were deemed eligible.

Results showed that insomnia was associated with all individual psychotic-like, dissociative and hypomanic experiences reviewed (effect size range: small-to-large). Parasomnias were associated with all psychotic-like experiences; however, there was evidence of variation in magnitude between individual experiences. An eveningness chronotype was associated with dissociative and hypomanic experiences, and circadian dysrhythmia was found alongside hypomania but not the other experiences reviewed.

Finally, experimental sleep manipulation studies revealed a potential causal link between sleep loss and psychotic-like and dissociative experiences, although size and consistency of effects varied by specific experience. Future research, using experimental manipulations of sleep to address putative mechanisms, will enable questions of causality to be answered with more confidence.

本综述旨在：1）确定与精神病样，解离和躁狂的经历同时发生的睡眠障碍；2）评估睡眠障碍的严重程度与所研究经历之间的潜在关联强度；3）评估因果关系的证据。检索了MedLine和PsycInfo，认为有44项研究合格。

结果显示，失眠与所有个人的精神病样，解离和躁狂的经历有关（影响大小范围：从小到大）。失眠与所有类似精神病的经历有关。但是，有证据表明，个人经历之间的差异很大。晚上的典型表型与解离和躁狂经验有关，并且昼夜节律不齐与躁狂症一起被发现，但其他经历并未被发现。

最后，实验性睡眠操纵研究揭示了睡眠丧失与精神病样和分离性经历之间的潜在因果关系，尽管效果的大小和一致性因具体经历而异。未来的研究将通过实验性的睡眠操作来解决推定的机制，从而使因果关系的问题得到更自信的回答。
