It depends the atmosphere
I always go to sleep on my right side, and when I wake up in the morning, I'm on my back spread out like a starfish.
I always hug my pillow, but i don't think that's actually that weird o.O
I like to sleep hunched over the back of the couch with my body pillow. Kinda like a fetal position.
I sleep like puppy
I shake my beaver until I get sleepy then I turn to side and sleep. You might find this immature but trust me when i say most men do this. Even when I had a gf, sometimes i'd prefer to do it myself then have s*x with her. Sounds sad, but when you've done it enough times you just want to do a little bit of self loving, just you and yourself. Sorry..i kind of diverted from your question.
Yea. men are very different in their sleeping rituals. Though sometimes I can't be bothered so instead i put some music on on my phone and just drift of (to give it some rest :P)
