Are you a light sleeper? Are you in controll of your body when your asleep?

I am a very light but yet sound sleeper. If there is a noise or a slight movement I tend to wake up, but then I can go right back to sleep. Myfriends and family make fun of my sleeping behaviour since I pretty much lay down one way and do not move at all throughout the entire night and I wake up in the same exact position. My bed never looks like it was even slept in.

HI, I am a light sleeper when I know I have children or elders around me. Other wise, I could and have slept through an earthquake. I have learned, I can have a full conversation on the phone, answer you and ask for things, all in my sleep. When I awake, I do not know any of this, until I am told later. I have had people call me and I never remembered one piece of it. Real strange. but, hey, at least I know when I am taking care of someone, I wake up on a move or sound. Strange how my body reacts, I guess, I know that I have no responsibilities when I am alone, so I am both a light sleeper and a heavy sleeper, thanks for the question
