Unlike @wenbow, I cannot sleep with socks or clothes on. I also only sleep best when I have my teddy bear-- His name is Big Ted; yes I'm 23 and still sleep with a stuffed animal, and no I'm not ashamed :)
I am much the same! I cannot sleep unless I am naked or nearly so. I have kids and so most of the time I sleep in just my underpants! Big Ted is a lucky bear to be so loved!
