Charlotte Perkins Gilman’s “The Yellow Wallpaper” is a clear-cut story of a woman’s descent from depression to insanity. The story, written as a personal journal by the narrator-protagonist—a woman whose name we never actually learn—details her own descent into madness from her own perspective. It is obvious to the reader by the end of the story that the narrator has gone insane; however, it is also obvious to the reader that the narrator doesn’t know this herself.
The introduction of the story outlines the mental situation of the narrator. The narrator knows from the start that she is not completely sound of mind, but insists that her physician husband “does not believe [she is] sick!” (8). The husband, named John, is convinced that the narrator is simply suffering from a “temporary nervous depression—a slight hysterical tendency” (9). John constantly prescribes cures for this hysterical tendency, but the efficacy of his cures is questionable at best. The narrator tells in her entries that her husband has her taking “phosphates or phosphites—whichever it is, and tonics, and journeys, and air, and exercise, and [that he forbids her] to ‘work’ until [she is] well again” (11). It is notable that phosphate is involved in ATP synthesis while phosphites are used in the production of pesticides and adhesive; take whatever meaning you wish from this. The narrator complains that she has “to be so sly about [her writing], or else [she is met] with heavy opposition” (15). The point of this paragraph is to explain that the narrator is suffering from some sort of mental instability and her husband’s actions are doing nothing to help.
The actual “yellow wallpaper” is part of the décor of the upstairs bedroom which the narrator and John choose to sleep in. The relationship between the narrator’s slide into insanity and this “almost revolting” “smoldering unclear yellow” (34) wallpaper is closely intertwined. The descriptions of the wallpaper in the beginning of the story describe it in concrete terms as “one of those sprawling flamboyant patterns committing every artistic sin” (32). But at the end of the story, the narrator starts seeing a woman in the pattern whom she actually begins to believe is real. Right before the story’s climax, the narrator is in the yellow-papered room by herself, but “really [she isn’t] alone a bit” (216) for she was in the company of the wallpaper woman! The narrator sees the wallpaper woman trying to escape from the design, noting that she “takes hold of the bars” which make up the pattern “and shakes them hard” (188). The narrator does her best to help the wallpaper woman escape, collaborating with her on a solitary night to pull off the wall covering, and “before morning [they] had peeled off yards of that paper” (217). The final manifestation of the narrator’s complete loss of mental capacity comes when she locks her husband out of the room and peels off all of the wallpaper.
A student of psychology may attribute the narrator’s insanity to two different things. Firstly, it is possible that the narrator is suffering from postpartum depression—not farfetched considering the fact that the narrator has a baby (mentioned in paragraph 46)—or maybe even postpartum psychosis, the symptoms of which, according to Wikipedia, include “seeing or hearing things that others don't” (i.e. the woman in the wallpaper), “random or uncontrollable anxiety attacks” (i.e. the narrator’s locking herself in the bedroom), and an “inability to take care of the baby” (i.e. the fact that the baby is hardly mentioned in the narrator’s journal at all). Secondly, the domineering demeanor of the husband may be exacerbating the narrator’s pre-existing mental conditions, but the narrator herself refuses to consciously admit it. The trapped woman in the wall is actually a “Freudian Projection”: the woman trapped behind the bars trying to escape the pattern is actually the narrator’s subconscious realizing her suppressed feelings of repression and constraint by John.
Freudian Projection is theoretically a psychological defense mechanism, which would project the narrator’s negative feelings away from her; however, her mental problems are apparently too great for this alone to work, which indicates that she is indeed suffering from some sort of psychosis. The end of the story, from paragraph 297 or so to the conclusion, outline the final descent into insanity. (724)
