REM Sleep
Captions available
The idea
REM sleep is a stage marked by rapid eye movements, brain activity resembling waking, and most vivid dreaming.
In practice
Recorded brain activity during REM is nearly indistinguishable from that of an alert waking person.
Where people slip
REM is not the deep stage. It is the active stage, and its share of the night grows toward morning.
