At the end of the story, the narrator creeps around the baseboards of the floor in the room where she has been confined. Her husband, John, walks in and promptly passes out, so she remarks that she simply crept right over him as she went around the room. It is a very eerie ending!
The narrator and Gilman has very similar experiences, but we cannot assume tha the narrator and the author are one-in-the-same. Sometimes the narrator closely resembles the author and sometimes not. In this case, Gilman did, in fact, get treatment for mental illness that was simliar to the narrator's treatment, so this story is based on many truths.
