where do dreams take place in the brain
Dream Accumulated observation has shown that dreams are strongly associated with REM rapid eye movement sleep, during which an electroencephalogram (EEG) shows brain activity that, among sleep states, is most like wakefulness. Participant-remembered dreams during NREM sleep are normally more mundane in comparison.[50] During a typical lifespan, a person spends a total of about six years dreaming[51] (which is about two hours each night).[52] Most dreams only last 5 to 20 minutes.[51] It is unknown where in the brain dreams originate, if there is a single origin for dreams or if multiple portions of the brain are involved, or what the purpose of dreaming is for the body or mind.
