What does it mean when you dream you're a clown?

I had a funny dream last night. I dreamt I was a clown doing a cookery routine with an Invisible Shelf. I kept putting things like the kettle on the Invisible Shelf and, because there wasn't a shelf there, they kept clattering to the floor and bashing me on the foot. At the end of the routine I had a tray with a plate of salmon sandwiches and a cup of tea. I put the tray on the Invisible Shelf and a pair of hands came through the wall and held it. The hands were wearing orange gloves, the same colour as the wall, so the audience couldn't see them. After the crowd applauded, I left the tray on the Invisible Shelf, drank the tea and passed around the sandwiches to show they were real.
