Not that he really understands some of them. Questioning the world around you being real? He has no idea how that would happen. The idea of seeing a world as 'artificial' is a strange concept. But he's learned enough that seeing an environment that's far too familiar might well be an uncomfortable experience. ]

But if you want to decorate...that's fine.
