REM Sleep Behavior Disorder
Even more rare, affecting less than 1% of the world’s population is REM Sleep Behavior Disorder (RBD). Those suffering from this sleep disorder act out their dreams due to a faulty brain mechanism that prevents any motor movement during sleep in those who do not have RBD. RBD causes sufferers to thrash around in bed, which can lead to injury (or an angry partner). Medication seems to be the only solution for RBD sufferers.
