Oh geesh; I can't stand to hear a TV while in bed. I don't understand watching TV in bed really. I do have a TV in the bedroom but the only time I might turn it on is to finish something I was watching when I decided to go up and get ready for bed. Every blue moon, if I'm just tired but not really sleepy I turn on a movie in the bedroom. I spend more time getting it set up and going than I watch, because as soon as my head hits the pillow it's lights out.
Watching TV with my husband before I sleep if it is the right programs can be very relaxing and often I begin drifting off during watching. But I have never needed TV to sleep.
I have no problems with falling to sleep. I watch old western movies on TV and in 10 minutes, I'm out. Once in a while I awake if there is an intense gunfight, or lots of screaming.
