That's right.
When people memetically post pictures of Shrek nowadays, he freaks out. He says that with all this following (shrekchan existing and all), Shrek has apparently ascended to some sort of god status in the astral.
I guess if he were to find out that Chris regularly converses with Sonichu, Rosechu and his other characters, and he even did once when confronted by MLW, he'd say that Chris isn't crazy or anything, he's just an entry-level tulpamancer (can't make tulpas actually interact with the physical world yet).
The way he believes all fictional universes to be real is kinda unclear on one thing - he places emphasis on the power of our imagination, but he'd also often say how all ideas we have come from the astral. So I don't know if all those universes keep popping up there from people imagining them, or if they've existed there all along and people making media with them are just messengers showing them to our world.
