Why we need to become unconscious in order to sleep?
An important detail which most commenters are apparently unaware of: You are still conscious while sleeping. Sleep is considered to be a state of altered consciousness, not unconsciousness. This is because you can still respond to stimuli while asleep, and wake up if necessary.
The Short Answer
An important detail which most commenters are apparently unaware of: You are still conscious while sleeping. Sleep is considered to be a state of altered consciousness, not unconsciousness. This is because you can still respond to stimuli while asleep, and wake up if necessary. In other words, everything is working normally while you're asleep. If you're unconscious, that means something is NOT working normally. Things that should wake you up aren't waking you up. Unconsciousness is a sign of something seriously wrong, e.g. brain injury, seizure, alcohol poisoning.
