Ugh, great. Someone is trying to wake him up back there now. He clings to his sleep for just a while longer.

"I don't think Prospit here works the same way as Prospit and Derse back home. You just poof out of existence when you wake up here, instead of your dream self falling asleep. Try jumping off a tall building. Die in a dream, wake up in real life." Since arriving in Rakuen, he's become fairly sure that that's the general rule.
