Cognitive neuroscience continues to build meaningful connections between affective behavior and human brain function. Within the biological and physiological sciences, a similar focus has taken place. This is the focusing on the role of sleep in various neurocognitive processes and, most recently, on the interaction between sleep and emotional regulation. This peer reviewed article gives a broad array of diverse findings across basic and clinical research domains, resulting in a convergent view of sleep-dependent emotional brain processing. On the basis of the neurobiology of sleep this article describes the overnight modulation of affective neural systems and the reprocessing of recent emotional experiences. Both seem to address the appropriate next-day reactivity of limbic and associated autonomic networks. Furthermore, a rapid eye movement (REM) sleep hypothesis of emotional-memory processing is proposed, the implications of which may provide brain-based insights into the association between sleep abnormalities and the initiation and maintenance of mood disturbances. This basis on REM sleep is quite influenced from the brain. The peribrachial area in the dorsal is part of the brainstem just anterior to the cerebellum. Therefore, these areas of the brain allow us to both sleep and dream in which are reoccurrences of events past, present, and future.
