The Yellow Wallpaper is told through the perspective of a woman who is slowly driven into insanity. First, she lacked human contact. Second, she was unable to distract herself from conflicting emotions. Third, John failed to support her when she needed it the most. Several foreshadowing elements open the story. But they reveal themselves only by the ending.
Throughout the plot, the yellow wallpaper often appears. Still, the woman perceives it differently each time. At first, it seems unpleasant to her. The color is too unclean, like her mind. Then the narrator tells about the broken greenhouses. The word “broken” in this case is a form of foreshadowing because it can describe broken (insane) people.
When the main character first enters her new house, she has a creepy feeling. It indicates her future “creeping” around the room. At one point, she described her home as a beautiful place, and in another moment, she could not stay there for too long. It is a symptom of bipolar disorder, as well as future hallucinations and schizophrenia.
The narrator discovered the teeth marks on the bed. It foretold that she would become insane. It also indicates that she never revealed the complete story of her illness. When the woman first mentioned the yellow wallpaper, it foreshadowed something wrong with the wall. This decor element could indicate her mental state, which also changed every moment of her existence.
