^^ this!
I also usually sleep in the center, though to be fair a single bed doesn't really have any sides.

I prefer sleeping on the couch instead of sleeping on my bed but I usually get told off for it

On the right because the wall is on the right. I sleep on my side (left or right side doesn't matter) and I like my back facing the wall. When the the bed gets a little hot, I just flip over my head and feet but stay on the same side of the bed.

I sleep alone in a double bed, yet I sleep on the left side. I think it's just so I can just slide out of bed easier when I wake up. It's a shame really, three people can fit in my bed, but im all alone

I don't share with anyone so I sleep in the center but on the side to the right curled up under the covers (my comforter is really really soft and comfy)

I usually sleep on the left side because the right side isn't comfortable, besides, if I sleep on the left side, I face the wall. Better than facing the door in the night, because I'm just that paranoid.
