"The Yellow Wall-paper": When Hallucinations Convey A Message

This anecdote definitely puzzles me. The protagonist is writing in a journal format about her stay her temporary home.
The main character seems to suffer from schizophrenia and postpartum depression. Her husband and her brother are respected physicians and choose not to acknowledge her "sickness". John, the husband, decides to rent a house for a couple of months for his wife to get better, providing her with the rest cure. Mary, a babysitter, is taking care of her child while she is receiving treatment. Jane, John's sister, watches over her the central character while John is at work. Her husband and her brother believe that the thought and creativity that come along with writing will not help her with her condition. Despite her family's belief, in the day time she writes in secret. At first, she is disgusted by the yellow wallpaper; the pattern, color, and quality makes her question who would live in that room. She realizes that the room was once a nursery. Her husband chooses that particular room for her confinement because it is large and airy. The windows have bars to prevent children from climbing out. Each day she is more intrigued by the wallpaper; she is determined to figure it out. She begins to hallucinate and see women creeping around the room, specifically along the walls. Later, she believes she sees the women out in the garden, running away. Towards the end, she is fixed on catching a creeping woman, which leads her husband to faint.
Charlotte Perkins Gilman herself suffered from schizophrenia and postpartum depression. It seems that this narrative mirrors her life. The creeping women may symbolize women during that time. In the story, the women creep during the day and remain at a standstill at night. Similarly, the main character writes or "creeps" during the day time while her husband is away and behaves during the night time. The men in the short story seem to high standing, while the women are doing chores (i.e. taking care of the baby and watching over the protagonist).
