Yes, it is related to true stories to an extent. The superstition of Friday the 13th being unlucky has roots in different cultural and religious beliefs. In some historical events, things that were considered bad happened on a Friday the 13th, which led to the spread of this superstition. The 'Friday the 13th' movies then capitalized on this existing superstition. They created fictional horror stories around it, making it a well - known horror franchise, but it all started with the real - life superstition about the day.
No way. Friday the 13th is just a made-up horror tale. There's no truth behind it. It's all about scaring movie-goers and having fun with the horror genre.
