Paradoxical sleep, also known as REM (rapid eye movement) sleep, is characterized by a high level of brain activity similar to that of waking, but with muscle activity suppressed, resulting in external calmness. This is the stage during which dreaming occurs. N2 and N3 stages are non-REM sleep stages characterized by slower brain activity and deeper sleep. N1 is also a non-REM stage, but it is the lightest stage of sleep.
