Peter's brain wave pattern of low frequency delta waves indicates that he is in either stage 3 or stage 4 of sleep, which are characterized by deep, restorative sleep. REM sleep, marked by high frequency beta waves, is typically associated with dreaming and muscle paralysis. Stage 1 and 2 are transitional stages between wakefulness and deeper sleep, with stage 2 characterized by the presence of sleep spindles and K complexes in brain wave activity.
