As a realist writer would you not think of them mad? Mad in the sense that the world is more than just black or white. Mad beyond political reformation and through harsh experience, trapped within the very cell of oppression. The Yellow Wallpaper has exploited a psychological realism by the narrator simply acting on her surroundings rather than reacting to them. Gilman as printed in Wikipedia, there lays the reason of her complex state, in between the lines is the very fuel that ignited such literature; that it created scandal in weaken minds that were subdued to bed rest.
A woman voice is what sings through the whirlwind of English terminology, it is not so much psychology as it is psychotic in the nature of society ruled by men. Granted her covering of grace was to be the haunted house she looked upon as being more than gracious to her fate but the cheapness in cost and its unkempt condition. All her hyperboles in the English language could have all been in correlation with her self-perception, who is not to say the very disorder in her home could not be the pandemonium of her depression.
In the beginning Gilman has personified the wall with giving it female attributes. A woman inside the paper, trapped, could easily be interpreted in the self delusions of her very medicated state. It could represent the very oppression on women in the 18th and 19th century of being the assignment by the male counterpart of just being obedient and silent. We get a glimpse of the very persona amplified by john's laughter, "one can only expect that in marriage." "John is a physician, and perhapsthat is the reason I do not get well faster. You see he does not believe I am sick!" (1660) John is practical, practiced in the rights for men; he only stimulates the very rise for a realist to expand their mind into the depths of inductive reasoning.
Gilman alludes to tragedy by hanging by a thread; there are thin lines of fabrication all that lies...
