iPhone time-lapse shows how much a 28-year-old man tosses and turns in his sleep

I've always wondered what I actually do when I sleep. Do I move around a lot? Am I in one position? Do I stay under the sheets? Using my iPhone 5s and time-lapse in iOS 8, I recorded myself for 6 hours on a Sunday night. I learned two things. I was completely disturbed watching myself sleep, and I couldn't believe how much I moved around the entire bed.
