Most vivid dreams happen during REM sleep
Vivid dreams predominantly occur during REM sleep, a phase of heightened brain activity vital for processing emotions and memories, impacting our mental health.
Most of our vivid dreams unfold during REM, or rapid eye movement, sleep phases. These periods of intense brain activity, discovered in 1953, can last up to an hour and are characterized by quick eye movements and temporary muscle paralysis. About 80% of dreams we recall come from REM, where the brain actively processes emotions and memories, crucial for learning and mental well-being. Disruptions to REM sleep, like from sleep apnea, can lead to mood issues or cognitive fog. Interestingly, some dreaming also occurs in non-REM stages, showing our minds are always busy creating narratives.
