How many pillows do you use to sleep?
ermmm ... I mean .... Technically, I only need the one for my head, but then I have one that fills in the space between my mattress and bed frame/mini headboardy thing, one that I use for extra back support when I sit in bed [I have no use for it laying down, but am told to keep it on the bed regardless], my actually back cushion (which... again, I only really use when I'm sitting >.>), and my body pillow that is mainly for my knees.... sooo I guess five-ish, not counting like decorative things or stuffed animal-pillow pet type things :P
Do you prefer fluffy pillows or firm ones?
Firm ... matress too ... everything has to be firm, and cold (preferably... I guess temperature doesn't actually matter that much since I usually cocoon myself in a blanket)
Do you sleep on your back, side, or stomach?
kinda depends on the night and how much pain I'm in tbh ... but usually I start on my right side. If I'm having a good night then I wake up the same way (or possibly having rolled to my stomach), if it's a rough one I may have created a whole new yoga position without even knowing it.
I also need strongly oppose the thought of not having my teddy (yes, I am an adult ... yes, I still sleep with a stuffed bear...). Though I don't consider the stuffed animal a pillow, a do basically cuddle with Teddy every night (unless I'm away ... I don't take it out of the house... I'd definitely loose it or rip it somehow).
