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.
