One of the best back stories in FNAF is about the Purple Guy. He was a serial killer who haunted the Freddy Fazbear's Pizza places. He caused the deaths of many children which led to the haunted nature of the animatronics. The animatronics, initially meant for family fun, became vessels for the vengeful spirits of the murdered kids.
Well, there's also FanFiction.net. It has been around for a long time and has a huge amount of FNAF fanfiction. You can find different types of stories there, from horror - themed ones that stay true to the original FNAF vibe to more light - hearted and creative interpretations. However, the quality can vary a lot, so you might need to do some sifting through the stories.
The Poughkeepsie Tapes is indeed fiction. It's not based on real events. The creators came up with the storyline and elements to scare and engage the audience.
The use of VHS in 'Pulp Fiction' adds a certain nostalgic and gritty feel. VHS was the common format at the time, and it gives the movie a sense of being a product of its era. It also reflects the kind of low - budget, underground aesthetic that the movie often presents.
The 'VHS 94 real story' might be related to a collection of short films or recordings on a VHS tape from 1994. It could be something like a compilation of amateur horror or mystery recordings. For example, it could be a bunch of local filmmakers' attempts at creating spooky content, which was then collected on this VHS. Without more context, it's hard to be more precise.
