Are there any books/stories that read like a ghost story, but the ghost turns out to be something else?

I’m looking for a good haunting, but with a twist. For some reason found myself wanting to read a ghost story that turned out not to actually be a ghost (or anything similar). The closest thing I can think of is Kneeknock Rise, the kids’ book where the “creature” turns out to be a natural phenomenon. Looking for something more adult-oriented and detailed than that, but it’s the general idea.
