Okay let me preface by saying I don't agree with it. I don't think this is good. I'm just putting myself in the heads of modern SE. If we assume that the stupid Dream World things are Lifestream soap bubbles where people work out their issues before dying then, in the most convoluted way imaginable, Sephiroth's goal is the same as FF7. He's trying to absorb the Lifestream, which by extension would include all the dream worlds. That big, stupid final battle against Bizarro Sephiroth was showing that he could do it already, he just was waiting for Aerith to die. And that the final battle in Rebirth was taking place within a Lifestream under Sephiroth's control. Which would explain how both Zack and Aerith are able to just wander in to help during the Final Battle. Both of them have Dream Worlds dedicated to them and so if Sephiroth took control of the Lifestream then that would include their worlds too.
Now if I'm correct, and again I realize this is stupid, then that hints at the source of Cloud's complete breakdown in the Northern Crater. If dead people who haven't diffused into the Lifestream can just show up in a world controlled by Sephiroth, that means everything Cloud lost can be restored. Aerith can come back. His mom can come back. Tifa can have her father back. Barret can have Myrna back. Maybe Vincent doesn't need to be a cuck. Fighting against Sephiroth would mean actively choosing to let go of the people who died. Something the party, but especially Cloud, would not be prepared to do. Remember Sephiroth explicitly said his goal is to invent eternity. While Aerith said even if you think this would be a good thing, it's not the way things are meant to be.
