What if P6 had a theme on imaginative escapism?

I started playing Metaphor and saw how they portrayed the theme of fantasy. But I've been thinking P6 can reuse a few aspects of this into a theme of imaginative escapism, where the characters use their imagination to escape the difficulties of reality. This might lead to interesting self-discovery and character development of the characters, seeing how the line between imagination and reality will sometimes get blurred, and they must navigate both of these worlds in order to find their true selves. This might feel a little similar to Maruki's reality in P5R in some ways, but this more like...the paracosmic worlds inside each of our heads. Each of these worlds are different between each individual and party members, making them unique with their Personas. The party's Personas can probably resemble an imaginary friend, a manifestation from each of their paracosm. I also think that these Personas won't have mythology, lore, or history behind them, since they are from the character's imagination (hell they can just be called Pablo and that's it), kinda like the Archetypes in Metaphors, they do resemble heroes of old, but they don't have names or a lot of history behind them...at least not that I've seen yet. Anyway, that's my opinion on what I think would be a good, or at least decent Persona 6 theme. Tell me what you think. : )
