I've had a Jazz-related dream before, too.
In the dream, I was using the Unreal Engine, and then this window popped up of a spinning 3D model of Jazz. And then suddenly, I was in the level I was looking at. Lori and Spaz were talking, and then Jazz walked in. Apparently they were waiting for Rayman. Rayman falls out of the sky, and I find out that I'm Rayman.
And then suddenly, I'm in my house. I walk out of the room I'm in, only to see a fire demon, who I then shoot with a gun that I suddenly have. And then I woke up.
