I generally vary between on my side and on my front. I usually fall sleep on my side and wake up on my front with my face smooshed at an odd angle and the douvet in disarray.
I usually sleep on my stomach. Sometimes my side. I try to avoid sleeping on my back because I wake up with sleep paralysis if I do.
Sometimes I get insomnia if I'm stressed out about something, but not often.
I have dreams most nights and sometimes I can remember multiple dreams in a single night, and I'm often lucid in them.
I only really snore or drool if I'm sick, but I've been told I grind my teeth. I used to sleepwalk and talk in my sleep when I was a kid, but I don't do that anymore.
I usually sleep in pajamas. Sometimes I'll sleep naked if I'm naked in bed already.
