REM Sleep Disorder: When Dreams Become Real

REM Sleep Behaviour Disorder (RBD) is a condition where individuals physically act out their dreams during sleep. Normally, muscles are paralyzed during REM sleep to prevent movement, but in RBD, this mechanism fails. This can result in shouting, kicking, or punching, often linked to vivid, action-packed dreams.

The disorder typically appears in the second half of the night and is often noticed by a bed partner due to sudden movements or vocalizations. Common warning signs include unexplained nighttime injuries and disturbances for the sleeping partner.
