I just want to point out another misunderstanding present in the title of this thread: Falling asleep is not an automatic death sentence.
You still have to roll to hit an unconscious creature (but you do have advantage on the roll), and you do still have to deal enough damage to kill it (but attacks from 5 feet away or less are automatic crits if they do hit).
So they're probably as good as dead, but it's not guaranteed.
