There's this idea I've had for a while of just going to a arena or something like that and entering a dream fighting competition where you get to fight against different competitors of all kinds. Maybe you could even add some extra challenges like only using a set of powers that is given to you. I think it's an interesting idea just to see what the dream throws against you. This is something I wil definitely try eventually. I challenge any willing dreamers to try it and post their results!
