I mostly sleep on my left side, on knee pulled up to my head. And I almost died trying to sleep on my face! I made four attempts to do it but always ended up gasping for air in order not to suffocate!
I somehow have a picture in mind how Fye comes into a room where Syaoran and Sakura wait, he wears that bandage is somewhat guided by Kuro where to go. Awww~ Pity I can't draw well enough to pull that off properly!
