This person is almost incoherent enough to be a comic book superhero for real. Maybe he hit his head on the way down. Yeah, that's pretty believable. Though are concussed people so chatty? The Doctor can't quite remember, and anyway some corrections are in order. "The Doctor. Definite article. And the answer to your question is 'whatever they feel like.' You're really very high and mighty for someone who eats off the floor. I can't blame you though, it is a dream. It is. Now you've been informed." The Doctor is doing a relatively stellar job of not getting fractious, minus the one quick snipe--getting to knowledgeably explain about the communal dreaming is pacifying.

"Specifically, a telepathically shared dream. One in which we apparently get to wear fancy dress, possibly a murder mystery party. That might be wishful thinking," he grudgingly admits, though what does floor-snack-man know, he can't prove anything. "Still, try to avoid people who look like they might be named after colours, just in case."
