Dreams are real IMO. The difference with the real world is that there are no other living organisms there. Basically you would be alone with your own subscouncious (<-- arguably) and mindless DC's. I think that is the reason why most people (including myself) wouldn't want it for eternity. Everything needs an opposite to be significant. If you can always do everything however you want it will become normal, and then it is like normal life but with brainless DC's instead of other humans. Again, all of this is arguable. And also, if you have something like a Dream Guide that CAN think for itself, it might be a different story alltogether.

Basically, whether one would want it or not depends on the way they experience things and the way they dream. That is different for everyone, so I don't think it is worth fighting over.
