What effect is created by not calling the woman in black by her real name?

Not calling the woman in black by her real name creates an air of mystery and detachment, emphasizing her otherworldly presence. It reinforces her role as a haunting figure, making her seem more like a symbol of grief and loss than an individual with a personal identity. This choice also heightens the tension and evokes fear, as it underscores her enigmatic and ominous nature throughout the story.
