REM sleep is characterized by which of the following?

Explanation:
REM sleep is a stage where the eyes move rapidly, and dreaming tends to be vivid. The brain shows activity that can resemble wakefulness—fast, irregular waves—while the body remains mostly paralyzed to prevent acting out dreams. This combination of rapid eye movements, dreaming, and a brain-type activity similar to wakefulness distinguishes REM from other sleep stages. The other descriptions fit different states: wakefulness shown by beta-like activity, deep non-REM sleep by slow delta waves, and REM is not dreamless or characterized by minimal autonomic changes (in fact, autonomic activity can be quite active during REM).
