She could very well be worried. You said, "I do not sleep good at night." I'll bet you toss and turn and even moan or mumble in your sleep. She's either confused and worried, or she is anticipating that you will wake up in a moment --- which it sounds like you do. I'm a "bad sleeper", too. My guys have pretty much learned where to sleep to keep from being kicked or rolled on or generally abused. And as soon as I make a noise, they're all like, "Mommie's waking up! Must be time to eat!"
