How do you sleep?

[Byue]

I am wondering how you guys sleep.
Usually on the side and since I am deaf, I sleep on my right side so I hear almost nothing.

Recently hurt myself rather significantly while sleeping.
Like I could barely move, for almost two days then it too me a week to recuperate.
How can you get hurt so badly while sleeping?

Do you guys have good posture tip, or sleeping technique to avoid snapping your own neck in your sleep, I kind of like living.
