I twitch in my sleep, snore, and I'M the one with PTSD! My poor wife. Ha ha. Sorry, just thought I'd put a little humor in here.

All seriousness, I can see how this would give you anxiety. I'm sorry that you have to endure angry outbursts over something you can't control. That is never ok.

Sounds like she needs to deal with her anger issues. My wife texts in bed and the little tapping sounds drive me nuts, but I find healthy ways to deal with it and not take it out on her.

Maybe you could see if she will meet you in the middle. You could get some help for your twitches and she could get some help with anger.
