An 'Unreliable' Source

I have found that literature has all kinds of parallels, metaphors, etc. I question the parallel in The Yellow Wallpaper. Could it be that the woman being set free from the paper is the on looker herself? Is it possible that the narrator rips up the paper to set free herself?
Have you ever told a story and realized there's a vital part you left out? Sometimes I have to go all the way back to the beginning to explain a certain detail to make my story more understandable to the listener. I think this is what is happening in this short story. Because of the narrator's condition her sense of time is skewed. She tells about her condition and confinement to the room with the gross yellow wallpaper. Could it be that she was the one who tore it up to begin with? Could it be that the bars were put on the windows to confine her? I wonder how reliable the narrator is as the story teller due to her condition.
I predict that John, the narrator's husband, put up the bars in the room with the yellow wallpaper. The narrator wants to include this fact in her story but forgets that they weren't there to begin with. She did not move in with the bars in place. Also, I think the narrator tore up the wallpaper herself. She wants a sense of freedom from her confinement. She seeks control of her own life. The narrator satisfies this by removing the wallpaper, releasing all the build up and stress from her own life.
