As the Fourth of July passes, the narrator reports that her family has just visited, leaving her more tired than ever. John threatens to send her to Weir Mitchell, the real-life physician under whose care Gilman had a nervous breakdown. The narrator is alone most of the time and says that she has become almost fond of the wallpaper and that attempting to figure out its pattern has become her primary entertainment. As her obsession grows, the sub-pattern of the wallpaper becomes clearer. It begins to resemble a woman “stooping down and creeping” behind the main pattern, which looks like the bars of a cage. Whenever the narrator tries to discuss leaving the house, John makes light of her concerns, effectively silencing her. Each time he does so, her disgusted fascination with the paper grows.
Soon the wallpaper dominates the narrator’s imagination. She becomes possessive and secretive, hiding her interest in the paper and making sure no one else examines it so that she can “find it out” on her own.
