This is something I have been thinking about a lot lately.
Is there any sensible reason why your brain absolutely needs to turn off your logic center almost completely while you dream?
What is the purpose of that?
Your brain is extremely active while you dream, so why does the logic center need to stop working properly?
I'm wondering because it makes no sense to me.
If dreaming used to be an important "training ground" for dangers in waking life, then wouldn't that kind of virtual reality simulation be much easier to take advantage of if you could think logically and be self-aware of your situation in those dreams?
Like "hah! now I'm dreaming! now I can practice running from lions and stuff all night so I can adapt to it more easily when I wake up!".
