I forgot most of the details, but the dream seemed to involve a program what was jumping between multiple different computer worlds, one of which was very similar in design to the old ENCOM system in the original movie, and another very similar to the Tron System. Every time that they jumped to a different grid, their appearance seemed to change accordingly. It was difficult for me to follow, and I don't remember any specific details about it. A shame, it would have made really cool story material.
