He begins to see trapped women dancing on the wallpaper in his room. Then he begins to crawl or "crawl" (in his words) around the room, running his hand in a line just above the base of the wall, until finally a crease appears in the wall from doing it all this time. Not only does it do this, but it also tears off almost all the wallpaper in the room. When John enters the room and sees this, she says, “I'm finally out of this, despite you and Jane. And I took out most of the paper, so you can't put me back! So it turns out that she ran away but had to go completely crazy and forget who she is to do it. She's escaped from her mind, which obviously isn't a good thing anyway, but more importantly, she's still trapped in the room with the yellow wallpaper. Not being able to think rationally, he will continue to “crawl” along that wall until he chooses to stop or until he is no longer physically able to do anything.
