REM sleep behaviour disorder (RBD) involves the loss of muscle paralysis during REM sleep, causing people to act out dreams, which are often vivid and violent. This review systematically examines studies on dream recall in RBD, using both retrospective and prospective designs, to provide a comprehensive overview of qualitative and quantitative dream features. The work highlights that studying dreaming in RBD helps understand unique aspects of the disorder and reveals neurobiological, electrophysiological, and cognitive mechanisms of REM sleep and dreaming.
