Wierd Dreams

The past two or three nights I've been having nightmares.

Last night Rick was in the dream, and he was carving the same symbols I saw on the wall by the bookstore into his arm.

I tried to stop him, he was crying as he carved (the knife was kinda blunt), but as soon as I touched his shoulder he turned to me and screamed "QUEEN OF HEARTS"! while pointing behind me. I turned around and saw a mirror.

The reflection wasn't me, it was the guy who I always see at the bookstore! I woke up laughing (?!) and then ran to the bathroom and puked...

I've got an appointment with a therapist (through school) tomorrow, I'm curious what this could POSSIBLY be?

I know I'm not crazy, obviously, but something's going on.
