AB Sleep  consists  of  two  distinct  states  as  shown  by  electroencephalographic  studies:  (1)  REM  (rapid  eye  movement)  sleep,  also  called  dream  sleep,  D  state  sleep,  or  paradoxic  sleep,  and  (2)  NREM  (non-REM)  sleep,  also  called  S  stage  sleep,  which  is  divided  into  stages  1,  2,  3,  and  4  and  is  recognizable  by  different  electroencephalographic  patterns.  Stages  3  and  4  are  “delta”  sleep.  Dreaming  occurs  mostly  in  REM  and  to  a  lesser  extent  in  NREM  sleep.
