Answer: Delusion and reality
Explanation: "The Yellow Wallpaper" is a short story that is written in first person by Charlotte Perkins Gilman. The story is about a woman who is taken to an old mansion in the countryside to rest. She was pushed to stay in a room without any stimulating activities by her husband and her sister-in-law. That lack of stimulation made her rave. She had some moments of delusion and some of reality.
