Sleeping habits

It takes me a long time to fall asleep at night, so I have lots of time to think about things while I'm laying there. And over the last couple of weeks I've noticed two things--I only roll counter-clockwise and I don't curl up, I curl down, which tends to result in me waking up halfway down the bed. But not only that, there's particular steps I take within the rolling, too. Here's what happens:

I'll lay down on my right side first. After a while, I'll roll onto my stomach, then I'll roll to my left side by pushing my left arm under my body to the right side.Then it's onto my back and I tuck my right foot under my right shoulder (I know this sounds impossible if you've never seen it, but it's a normal way to relax for me!) then back to my right side again, the whole process repeating any number of times. And on each side, my hands, feet and legs have set places to go. Regardless of how long it takes, though, I always sleep on my stomach.

All this made me wonder...does everyone have habits like this, or am I just odd? Cuz Mike lays down on his back and he's asleep in two minutes. I suppose probably everyone has their own little habits, but being that you sleep from birth, most people don't notice them all that much. And I'd imagine most people don't really care, either...
