Your brain paralyses your body every night.
During REM sleep — the stage where dreams happen — the brain blocks most muscle signals so you don’t physically act out what you’re dreaming.
Your mind might be running through intense scenes…
but your body stays completely still.
It’s a built-in safety system your brain turns on every night.
