To sleep, perchance to DREEEEAM?!?!?!?!

So, I had another random dream yesterday night. ( I have the weirdest dreams ever )

Yeah.

So, anyway, during this dream, I experienced "dream deja vu". Like, you feel that you've had the dream before. Not necessarily in a recurring dream kind of sense, but you think that things went differently last time. I'm curious: does this happen to anyone else? Or are my dreams just so weird that they include metatextual commentary as well as copious amounts of crack?
