What If... Spira was the dream?

[Zanmato]

I always never bought that it was a dream, I always thought it made more sence story wise to have it as a alt universe myself. How do dreams have memories, how can a dream be a tangible thing that feels. That's just what I always thought of it.

It's quite possible, I give you that, but Angus' theory makes more sense to me and it's closer to the truth than any other.
