During paradoxical sleep (also known as REM sleep), brain neurotransmitter activity in the pathways regulating states of consciousness is similar to that in the awake state. This means that although the person's muscles are paralyzed and they are difficult to awaken, their brain activity resembles that of being awake, indicating that their brain is actively engaged in dreaming and cognitive processes.
