"Tempting, but I don't think I could handle the responsibility." Was that funny, or just dream-funny? Well, to the TARDIS, probably neither, but that's its own brand of comfort, paradoxically familiar and archaic. And objectively it's probably only the latter. Jokes, and insults, they never really hold up under the light of day, when they're the product of a mind left out to figuratively graze and ruminate. "Maybe just for special occasions and particularly windy days. Are there very many of these dreams that don't go immediately pear-shaped in some way?" He sounds only very mildly curious about the ratio of unpleasant communal dreams to those that are relatively harmless, like the beach with the spiritual manifestation animals. The beach had been nice. The forest had not. Does it alternate, is it just a roll of the dice? Do they vote with their subconscious minds? If someone has a really bad day, can they spoil the dream for everyone? "Which do you think this is?"
