The Yellow Wallpaper

Ok, so I realized way too late (as in I had read the whole story by that point) there was an explanation at the beginning about the story, however, I think I will go ahead and write from my perspective.  During her first description of the situation, I believed everything she said: the nerves, her vacation, the way her husband did not take her seriously...I believed it.  What made it most believable was her description of her "nervousness" being linked to "histeria" or "histerics" which many men believed to be a "woman thing." All of this convinced me until she began to describe the bedroom.  Weirdly enough, it was not the barred windows, or the holes in the wall, the gashes in the paper, that caught my attention.  It was the bolted bed.  I can believe a nursery would have had all sorts of wounds inflicted by children and that the windows would be barred seeing as they are on the second floor, but a bolted bed? This clued me into her situation.  From then on her obsession with the wallpaper and the woman she saw in the paper all were supporting my belief that she was under someone's care and dwelt in a world mostly of her making.  The final piece of information that confirmed my suspicions was the following, "I always lock the door when I creep by daylight.  I can't do it at night, for I know John would suspect something at once."  First of all, she was telling me about the woman who creeps and now she has admitted she creeps! She is the woman, and she speaks of suspicion.  Of what? So she knows John and Jennie are watching her because she creeps. However, why did he faint in the end?  The truth is, I am not really sure what creeping looks like, but it sounded like it would have made me faint too.
