I dreamt I was watching a rape once, that was a bit weird. And I've had quite a few Coneheads dreams, "man you guys look freakin ridiculous".
My recurring car crash nightmare is weird in that I always awake from it in a cold sweat, even though it isn't particularly scary.
But the weirdest dreams off all are the ones where you dream of an ordinary conversation with someone you know, but everything they are saying is not at all the type of thing they would say. Then when you wake up and recall the dream you think: "hey, that was weird, I just dreamt of normal conversation. Wait a second, he said WHAT!?"
"Try and lay an egg."
