Most of the Pinterest ghost stories are likely a mix of truth and fiction. There are some that might start from a real encounter someone had with something unexplained. However, as the story gets shared around, details can get exaggerated. Also, some are probably completely fictional, created by those who love to write spooky tales and share them on Pinterest for the thrill of it.
