But... I don't even watch Supernatural!

So what are Dean and Sam doing wandering around in my dreams? And why, if they insist on being there can't they be out of character, instead of being their obnoxious, snarky selves? Not only were they following me around the countryside in their oh-so-not-inconspicuous car, but they (well, mostly Dean) kept bickering with me on how I must have some "supernatural" connection because I noticed them. Yeah, Dean, you blend right in.

Most people dream in color; why, oh why, do I dream in canon?
