Losing consciousness, defenseless, this doesn’t seem like a good idea from a survival standpoint, especially for a little furry creature in the wilderness that’s trying not to be eaten. You have to sleep or you get sick and you die. And this doesn’t seem to have anything to do with humans having such complex brains - fish sleep, cats sleep, it’s even possible that little microscopic lifeforms like blue-green algae might sleep.
