[00:00:00]You're in the middle of a nightmare, running, almost caught, and right at the worst possible moment, you wake up.

[00:00:08]But here's what nobody questions. How did the dream know exactly when to end?

[00:00:12]Because it did know.

[00:00:14]Scientists discovered that your brain monitors outside sounds and sensations even during deep sleep.

[00:00:19]It weaves them into your dream in real time, building a storyline around them until [music] the signal gets too strong to ignore.

[00:00:26]Your alarm doesn't interrupt your dream.

[00:00:28]Your brain writes the alarm into the dream first.

[00:00:31]Then wakes [music] you after.

[00:00:33]But the deeper mystery is this. Who is the writer?

[00:00:36]Your unconscious.

[00:00:38]You're not [music] deciding anything.

[00:00:40]Yet something inside you is actively constructing entire worlds, storylines, [music] and characters in real time.

[00:00:46]Every single night.

[00:00:48]Without your permission.

[00:00:49]Without your awareness.

[00:00:51]Something in you is creating.

[00:00:53]And you wake up remembering almost none of it.
