The fnaf short stories often involve the spooky and mysterious events in the Five Nights at Freddy's universe. They usually center around the haunted animatronics in Freddy Fazbear's Pizza place. For example, there could be stories about the night guards' experiences facing these creepy animatronics during their shifts.
The main characters usually include the night guards. They are the ones who have to endure the terrors of the haunted animatronics during their shifts at Freddy Fazbear's.
Definitely not a true story. FNAF is a work of fiction that takes place in a fictional world with its own set of rules and scenarios. It's all about creating a thrilling and immersive gaming and storytelling experience, not reflecting reality.
The mystery surrounding the backstories of the animatronics is quite scary. You don't know what really happened to them before they became these haunted - like beings. It makes you wonder what kind of dark secrets are hidden within their mechanical frames. And as you read through the stories, the sense of dread builds up as you learn more about their possible motives for scaring the characters in the stories.
One book similar to the FNAF story is 'The Silver Eyes' by Scott Cawthon. It has a similar spooky atmosphere with mysterious events and animatronics that seem to have a life of their own.
