Want to know what happens when we dream? Don’t miss these shocking facts… #dream #sleep

So what happens when we're dreaming? You're dreaming state. The thalamus opens back up a little bit, but only for certain things. It doesn't open up to the outside. It opens up only to internal sensations, to the brain cortex. So these internal sensations, it opens up to. The purpose, like we said, for dreaming is integrate kind of the current learning into your model of the world. We all have this model of the world. They're all trying to learn about the world. And really kind of comes back to two things. The two main motivations for us from a biological standpoint are preservation of the self and preservation of the species. Everything goes back to that. So we're always trying to figure out this model of the world, right? And perfect our model of the world so that we can survive in the best way. And that's so we can procreate, basically keep the species going. What they have learned, though, is people think, oh, I'm just replaying the day's events, whatever happened that day. What they've shown is that only 2% of that happens. They study people and they ask them what.
