I prefer to sleep with a fan on so I don't hear the little noises.
Either that or if I'm somewhere without a fan I bring ear plugs.
I pick things... like lint balls or something on socks. I make a mess but I can't stop. If there are any on a chair, blanket, clothes, I'll find em and pick at them till I get them all or ruin the clothes.

It's like bumps on things that should be smooth bother me and I pick at them.
