Yellow Wallpaper

In "The Yellow Wallpaper," I think the narrator suffers from a nervous condition. Her husband who is a doctor, recommends that she recuperate in solitude. He forbids her to write, because he insists it is to taxing, so she writes her journals in secret. She sleeps in a large room she believes was once a nursery. The room contains a bed, barred windows and "UGLY" yellow wallpaper. The woman slowly becomes obsessed with the wallpaper. Sha stares at the pattern and evetually decides that it depicts a woman trapped behind bars. Ultimately she locks herself in the room and starts peeling the paper off the walls, she begins to think that she is part of the wallpaper pattern and crawls along the floor following the pattern. Her husband returns home to find her crawling along the floor. He faints across her path, and she continues to crawl over him.
I found it interesting that although men are controlling women throughout most of the story, that he would faint at the end, with his wife crawling on top of him (maybe showing weakness and the eveyual triumph of women ?). Was it really a nursery she was living in, or were the items in the room contraints for the crazy woman, was she really the one that was crazy, or was it John?
