This awesome lady plays a very important role. She is described as being a woman of exquisite beauty. While reading we see how the speaker is obsessed with her, he always brings her up; he doesn’t see anything bad in this woman. She was a lady of his dreams, and even when he tries to think about something else, he always catches himself that he started thinking about her again. But we don’t know that much about her to characterise. That’s why we can’t comprehend how she looks like, who she is for the narrator. She looks like an idea, a memory but not a real character.
