in my dream. it was moldy and had tomatoes and pickles and mayo on it and i hit him in the eye with it. he wasn't very happy about it, either. he had red hair and he was trying to scam me. i told my boyfriend about it during my dream as well. i was trying to explain how i beat up a guy with a sandwich. he was very impressed in my dream (and this morning on the way to work when i actually did tell him.)
it was actually extremely satisfying.... i can never punch anyone in my dreams. like my fist just goes really slowly and then if it connects at all, it's like the worst girl-punch ever. "uh. take that." it always upsets me because i can never fight anyone scary in my dreams; i either have to run away from them or try to reason with them. but apparently i can hit them with a weapon (um, like a sandwich)... it's probably some deep-seated martyr complex
