For the most part, I sleep on the floor, with a blanket and a pillow. I have a bed, but I never use it unless I change the sheets. And after sleeping on the sheets just once, I remove them the next day. I refuse to sleep on them more than once. It doesn't make sense to most, but that's a habit I've got. I feel that once I sleep on the bed it's no longer pure until a new sheet is in place.
I have the weirdest of traits (not literally, but yeah.. they are pretty weird).
