There are narrators who uses a single point of view while others use varying points of view.
As long as these point of views are needed to give additional details about the characters or create tension in the story to make the plot move forward, the use of various points of views is necessary.
In the story, The Yellow Wallpaper, the first person point of view is being used. The narrator is the main character, Jane. Through her own views, thoughts, and perceptions, the audience feel as though they are part of the story and sometimes empathize with the Jane and what she is going through.
