Your wife’s behavior is extreme.

But I concerned about other stuff...

I’d check with your doctor about your breathing. You might need to see respiratory specialist. “Jerk waking up/twitching”might be a sign of a trouble breathing in your sleep, my husband has central sleep apnea associated with Tourette’s. If he doses off without bi pap, he immediately wakes up with a twitch. He doesn’t do it often because he knows better. According to his respiratory doctor he could pretty much pass away at night or during nap if he doesn’t wear bi pap. His body doesn’t remember to send a signal to breath

Now as about tv. If you want to sleep and she wants to watch tv, she should watch it on a tablet/iPad with headphones or read ebooks. That’s what we do if one of us wants to sleep and the other is still wide awake. We don’t keep tv in the bedroom, only in a living room. Individual devices work just fine in the bedroom for those occasions
