Decorating tips for college dorm?

i'm starting college in the fall, and i'm not sure how to decorate my dorm. i know that i want a black/white zebra stripe comforter with one set of light pink sheets and one set of hot pink sheets. but other than that i'm not sure what to do. basically the rules are: no nails/tacks in the wall, no blocking emergency lights/smoke detectors/fire exits, and no destroying furniture. any ideas?
