I've read we rehearse things in our dreams. If we played tennis one day, we simulate playing tennis in our dreams that night, and the next day we are better at tennis.
I also kind of wonder - does sleep have an evolutionary function to not move and not make noise during the night to patiently pass the time of night predators?
- yard2010 3y agoI can't remember where but I read somewhere a theory that says that most of life started sleeping, in the water, this was the default state. At one point in time stuff started being awake and developed wake consciousness, and the evolutionary pressure was on the wakefulness of things, because if one thing is awake everything has to be eventually. It made me think - why are we thinking our wake life is real life? When we're asleep - we're sure the dream world is the real world. It's like one life is not enough from an evolutionary standpoint. You have to have 2 lives, interconnected on 2 different dimensions, alternating day and night.
