And do they have pajamas in space?

After I inquired whether or not they're doing it in space, it occurred to me to wonder whether or not they have pajamas in space. And what about lingerie? In fact, how do they sleep in space at all? Do they even have beds? I guess they have to strap themselves in or something.

Sorry if I seem too concerned with sleeping arrangements up there. I know as a good citizen I should be more concerned with whether Iraq has weapons of mass destruction, but frankly this seems much more interesting.

And what about dreams? Are dreams any different in space, while sleeping in free fall? I'm not sure I've ever heard anything on the subject. Except in science fiction of course, which is just one giant space dream.
