The best explanation I have seen for dreams, to put it very simply, is its just our imagination running wild. Our brains arent focusing on any real thought, so they just go to imagining things.

Why do humans actually need to sleep I heard once (not sure if its true) that there was one man who 'never' slept because he believed that humans did not actually need to and we only do because we are used to it from when we are a baby.. What is the actual reason we need sleep is it because our brains need rest.. well say if you didnt sleep for 2 days or 4 days your brain would still work just as good right? Rating: 5
