Well, I once had a Bionicle dream in which I went to a store and I found a Toa Metru Ownea for $10, which the canister and instructions and everything, but my parents refused to let me buy it. That sucked because I wanted it sooo bad!
I also had this really weird dream about the Flash. Basically I found out there was another TV show about the flash, only instead of Barry Allen it was some random kid (Who I'm going to call T.J, since I can't remember his original name) I remember that there was this villain who was causing these buildings to disappear and reappear, and Joe West was trying to stop them along with this young flash, and Green Arrow (Which I assumed was foreshadowing an Arrow/Flash crossover was going to happen some day) and then the Reverse Flash, who was really old for some reason, came in and tried to stop the kid, but he failed.
Also there were these people trying on clothes that gave them super powers, as well as the same kid at a rail road trying to stop someone else.
My dreams are so weird.
