"If you insist." He's definitely amused, but given that he's currently not bothering projecting emotions for a facade, it's probably not terribly obvious. "Perhaps if you need something else to think about, something like... dreams, perhaps? Would be safe enough."

That, and he really feels oddly cut off, not being able to freely interact with the dream world.
