Thoughts on "The Yellow Wallpaper"

I enjoyed the stories written by Poe, but they were more humors to me than scary, whereas The Yellow Wallpaper genuinely creeped me out. I'm not sure if anyone else had this thought or interpretation, but throughout the story I was wondering if the woman was actually crazier than she realized. The fact that she was staying in an old mansion where the beds were nailed down, the windows were barred, she didn't get to choose her bed room, and her 'husband' was a doctor, made me think she could actually be staying in a mental institution and that she was delusional about the situation.  This actually really got me thinking about how much we can believe from a person who we label as crazy. How can we tell what is real or an illusion or actually supernatural when an entire story is told from a person whose mental status we question. In the first lecture we talked about how Todorov defined the genre of fantasy, and how it lied in the space between accepting and denying/rationalizing a seeming supernatural event. It seems to me that using the perspective of a mentally ill person is perfect for this genre, because we are constantly in the state of questioning if everything they see or say is real.
