Ideas for Virtual Reality Spells

If you play Italo Calvino, you can say "stories" and it enhances the urban ambiance (Calvino is the author of Invisible Cities).

If you play a magical realist, such as Borges, you can say "twisty passages" and the story gets confusingly enchanted (Borges is the author of The Garden of Forking Paths).

If you play a Latin American writer, you can say "he was still there" and everything gets minimalistic (Augusto Monterroso wrote the famous minimalist poem, The Dinosaur, which ends similarly).

Or, perhaps a personality survey can give differing levels of magic power, within categories defined by similarly interesting subjects.
