How do you not call 911 with a cracked head, yet someone crawl into bed?
What may appear to be a minor head bump can be very deceptive. Most people aren’t going to the ER if they don’t think it is very serious.
Many years ago I read where a man banged his head on the pipe under his kitchen sink. Thought nothing of it. He died a couple of days later of a blood clot that formed and went the wrong way.
It is the nature of the universe to be sneaky and cruel.

You fall down and crack your head, it hurts but you feel mostly okay with a headache. You have a brain bleed and go to bed a little bit pissed off about falling down. The brain bleed kills you in your sleep.
