The thing about the sleep of cavemen is we don't know how they slept exactly, but what we do know is we studied people in Tanzania, so the Hanzo tribe, and they still live in the same circumstances as probably we did when we were cavemen. And what you can say is that they were actually quite a lot awake during the night, so that being awake during the night was quite normal.
