First of all, let me just say that xkcd is quickly becoming a cultural touchstone for me. The most recent comic is particularly interesting, because I'm always amazed at how people have similar stress dreams (teeth falling out, the actor's nightmare, etc.) for no obvious reason. My version of the one from the comic is sometimes actually in high school, and other times in college. Haven't had it in a while (though, now I'm almost assured to soon).
