Do Dreams Seen in the Last Part of the Night Come True? Part 2: Science, Psychology, Culture, and Common Experiences The Science Behind REM Sleep Sleep is divided into several stages that repeat throughout the night. One of the most important stages is Rapid Eye Movement (REM) sleep, during which the brain becomes highly active. Although the body remains mostly still, the mind is processing memories, emotions, and experiences. Research has shown that REM sleep periods become longer during the final hours of the night. Because many people wake up during or immediately after this stage, the dreams they experience are usually remembered more clearly than dreams from earlier in the night.
