I dreamt that a few friends and I were on a conveyor belt moving around and past all of the restaurant windows in Chinatown.  Each restaurant had a panel of checkerboard-like windows in front with one kind of food pictured on each pane.  I was demonstrating to the others how, as you travel by, to order food, you just use a mallet to break the windows of the things you want.   One person asked me, “What do you do if you change your mind?”
