A group of girls asked this and they were telling everyone it was gross, but some people said they do. They asked a couple teachers, and they had interesting and mixed responses.
I can sleep with or without socks on, even if it is 100 degrees outside. The thing is, I always end up with one sock on, though.
Sometimes I sleep with my socks off, but I'd say it is 50/50.
I usually sleep with my socks off. I don't really enjoy wearing socks or shoes. The only time I sleep with socks on is if I fall asleep with them on because I just didn't feel like taking them off or, if my feet are really cold, which doesn't happen that often. If I do have my socks on while I'm sleeping I wake up the next morning and at least one of them is off.
At one point when i was about 6, i slept in all my cloths (shoes included) so that i wouldn't have to get dressed in the morning.
I do that rather frequently, actually. And if there's someone out there who documents what I wear every day, they wouldn't be able to penalize me without telling me that they document what I wear every day.
I usually don't sleep with my socks on because I have very hairy ankles, and having the sock there all day can get very irritating after a while.
