REM sleep has a low-voltage, mixed-frequency pattern on EEGs and is considered dream sleep. In this stage, the body has a complete loss of muscle tone, known as flaccid paralysis, and it cannot move. During this part of sleep, consolidation of memories may occur, but disagreement still exists as to what takes place with regard to memory during REM sleep.
