Red sensing Aerith is too intentional for me to think it's ALL in Cloud's head

One more theory that would explain this. We've only seen a few people sensitive to the lifestream. Aerith and Seph seem to be able to manipulate it and jump around on demand. Cloud and Zack can traverse it but can't control it. Red can just sense it.

Aerith can do so because she's Cetra. The rest only have 1 commonality, which is that Hojo did some mako shenanigans on them. Hojo accidentally tuned them into the lifestream. Zack and Cloud had the heaviest dose, so they are more sensitive to it, and specifically attuned to each other's consciousnesses. Aerith helps their sensitivity too, especially Cloud's. But even before meeting Aerith, Cloud channeled a ton of Zack's lifestream, which is how he was able to become so strong in under a week. The Seph clones channel Seph's lifestream in the same way (but weaker), which is how Roche got stronger and became able to do some Heartless Angel style attacks.

Seph got some lifestream sensitivity at some point, but started going deeper with the help of Jenova. In the Japanese, he mentions that he absorbed all of the Ancient's knowledge, which is probably how he became able to manipulate the lifestream like a Cetra.
