[00:00:00]Why do you always [music] wake up right before the worst moment in a nightmare?

[00:00:04]It is not luck. Your brain deliberately pulls you out before things get any worse. As a nightmare escalates, your amygdala, the part of your brain that processes [music] fear, begins firing more and more intensely. That escalating activity triggers a surge of cortisol and adrenaline, flooding your body with the same stress response [music] it would produce during a real emergency.

[00:00:22]When that stress response crosses a threshold, your brainstem [music] forces your body out of REM sleep entirely to protect you from the psychological damage of experiencing the full event.

[00:00:32]The worse the nightmare gets, the [music] faster and harder your brain pulls the emergency exit. So, the next time a nightmare jolts you awake right at the worst possible second, your brain did not fail to finish the dream. It decided you had already seen enough and shut the whole thing down before it could go any further.
