Here's why she isn't real:
* Fictional Creation: J.K. Rowling created Moaning Myrtle as part of her magical world.
* Literary Purpose: Myrtle serves a purpose in the story by providing information, comedic relief, and a sense of the supernatural.
* No Historical Basis: There is no evidence to suggest that a ghost like Moaning Myrtle ever existed.
While it's fun to imagine ghosts in our world, Moaning Myrtle remains a captivating fictional character within the Harry Potter universe.
