My son is 18 and he knows not to even come into my room until I'm completely awake. He barely sticks his head in the door. (We had a bad experience with him taping me on my shoulder while I was asleep once) Unfortunately he had to learn the hard way and you might want to tell your son not to come in on you like that or he might have a bad experience too.

I hope your nights get better soon and you move out of hell and into peace.
