Hallucinogenic Mushrooms, Or Just Child’s Play?

I stepped out of my home office to check on my four-year-old and Stiles playing in the living room. He was playing the role of a stuffed owl, and she was playing the role of Spongebob, I think. I’m not sure what the imaginary situation was but it involved several books displayed on the couch. Maybe some sort of museum? When they were talking in their characters, it sounded like they were in a different realm. I had to ask: “Are y’all in the spirit world?”
