I have had this idea for a while.

Basically, there would be a collection of lucid dreamers, and they would collaborate, and create an idea for a dream world, with factions, characters, and a storyline. Each dreamer would create a character to be. Every time the dreamer has a lucid, they would assume the role of their character, and they would progress the story. It would be kind of difficult to manage, and there would probably be a lot of dispute over things that happened, but I think it's a cool idea, in theory.

What do you guys think?
