The Science of Surrender: Why Drooling Happens

During deep sleep—especially in the dream-rich REM stage—your brain initiates a protective state called atonia. This temporary muscle paralysis prevents you from physically acting out your dreams (imagine sleep-walking through a nightmare!). It’s your brain’s elegant safety mechanism.
