Today's Random Fact:
During sleep, the brain "consolidates" memories and skills, meaning that the brain strengthens, reorganizes, and restructures memories during sleep.
REM atonia, or sleep paralysis, occurs in the typical sleeper every night to prevent people from acting out their dreams. Only a few muscles have the ability to move during REM sleep, such as the eye muscles, the auditory muscles, and the diaphragm for respiration.
