You don't say, but getting back in touch with Erin did indeed relieve Yu Sheng—he also had to admit, even though this little doll sometimes spoke offensively, this time she really did reveal some very useful information.
In the real world, he was indeed still "dreaming," but it was clearly different from the normal dream entrance; Erin thought his consciousness was "lost," which meant...
Yu Sheng lifted his head and looked around the cozy little cottage, and through the window, at the vast night sky beyond.
This "forest"... is an existing "Spirit Space" somewhere, complete and enclosed, like a trap, pulling the dream walker's spirit into it while cutting off any contact with the outside world.
Thinking of it that way, Erin seemed pretty impressive—how did she manage to find him under these circumstances?
