Another wasn't messing with demons and multiple spirits, it was a single ghost story with a plot twist.
The thing is ghost stories come from somewhere, the ones passed down through generations, something happened that makes people want to warn others of the danger, but since they can't tell people the truth because they will not be taken seriously, came superstitions and what not, a way to pass down knowledge through generations to warn of malicious spirits and odd happenings.
Then again I'm the kind of person who when accidentally spilling salt will toss it over her shoulders without even thinking.
