ELI5: What causes us to not say to ourselves "this is totally unrealistic" in dreams?

Why do we lose our sense of reality while dreaming? Not once during my dreams do I think "it doesn't make any sense that I'm able to fly right now."

When we fall asleep, our brain activity is sharply lower than it is during the day: and while parts of your brain may still be functioning while you sleep, you **usually** don't have access to advanced logic in your dreams.


However, it is possible to realize you are dreaming, and lucid dreaming is a thing some people practice. Lucid dreaming involves, oddly enough, tricking your body into being asleep, while most of your brain stays "awake" in a sense.
