There he met John Doe who explained that in order for him to enter the real world he needs Yumeji's body. Yumeji scared of this, tried to run away.

Quotes

 * (To Yumeji) "Deja vu is a sign of the intersection between dream and reality. Welcome, boy. Or should I say, thank you for accepting my invitation. My name is Chaser John Doe. As you visit our world, so I too have come to visit yours. But, I need a vessel from the other side to come out... You'll have to excuse me, but I'll be making use of your body. There's nothing to be afraid of. You'll be just asleep for a while. Now!"
 * (To Merry) "My apologies, little sheep. I'm headed the other way. I've come here to get outside."
