[00:00:00]When you wake up suddenly at night, your body might be completely locked independently of your mind. If you experience this, your brain is stuck in the REM stage, the deepest phase of the sleep cycle. While the pons region normally paralyzes your muscles, your consciousness wakes up seconds before this protection ends. At that exact moment, because your respiratory muscles are suppressed, you feel a 100-lb weight on your chest. Thereupon, the panicking amygdala region interprets the dark shadows in the room as imminent threats.

[00:00:36]Fear chemicals flood your entire body, yet your motor cortex cannot [music] send a signal even to your fingertips.
