What Happens
You wake up — but your body doesn't
REM atonia — the protective paralysis that prevents acting out dreams — persists after your mind wakes. You are conscious, but muscles are locked.
Fear activates before logic
The amygdala fires immediately. The prefrontal cortex is still booting up. Your brain sees a threat — but can't rationalize it away.
The hallucinations begin
Dream imagery overlays onto the real room: a dark presence, pressure on your chest, a figure in the doorway, difficulty breathing.
Every culture creates its demon
Same neurology, different mythology: Slavic Mora, Japanese Kanashibari, Chinese ghost pressing bed, Mexican dead man climbing on you.
