1. You feel like you’ve woken up dead.
Basically your mind wakes up but your body doesn’t, so you essentially feel trapped inside of your body unable to move. Many people wake up feeling like they’re dead.
2. It happens as you fall asleep and wake up.
Sleep paralysis can happen during either of the two transitions in your natural sleep cycle. Your body goes into REM and must eventually come out, but sleep paralysis happens when your body has trouble making the transition.
