Well, 'noticed' is another word for'seen'. When it comes to 'novel', 'original' is a great alternative. The word'seen' implies the act of visually perceiving something, and 'noticed' has a similar meaning but might imply a bit more of an awareness. 'Novel' means new and different, and 'original' also gives the sense of being new and not a copy.
Haunting narratives. Ghost stories are often about things that are spooky and haunting, so these words can be used to describe them in a different way. For example, a 'haunting narrative' might imply a story that stays with you long after you've heard it, much like a good ghost story does.
Tales. Tales can be long or short, but when we talk about long stories, 'tales' can also be used. For instance, 'fairy tales' can be quite long when they are fully developed, with complex plots and multiple characters.
