Once we are conscious, the peak of the waves is low and the waves are reasonably rapid. By contrast, all over sleep, the waves get upper and slower.
Non-REM Level 3 has the tallest and slowest waves of all of the sleep phases. In REM sleep, mind waves are low in amplitude and reasonably rapid, and the attention actions are speedy, too. Other folks want each non-REM and REM phases for a wholesome mind, so they may be able to be told and consider.
