3. Sleep Stages 3 & 4
The third stage of sleep is deep sleep or delta sleep, as the brain creates slow, delta waves. During stage 3, the body's cells repair and regenerate. This stage is the hardest to wake someone from, and those woken may be confused and disorientated for a few moments.
The final stage is REM sleep. During this stage, brain activity is at the same level as someone who is awake, but the muscles are paralyzed, except in cases of sleepwalkers.4‘Stages of Sleep.’ Sleep Foundation, www.sleepfoundation.org/how-sleep-works/stages-of-sleep.
