The Fears to Fathom stories are purely fictional. They're designed to give you a thrilling and spooky experience, but not to represent real-life situations or events.
Well, in 'Fears to Fathom', there are real stories like the one where a person moves into a new apartment only to find that there are unexplained events. For example, objects moving on their own. Also, there could be a real story about a hiker who gets caught in a sudden, terrifying storm on a mountain and has to struggle to find shelter. And perhaps a story of a person who wakes up in a strange place with no memory of how they got there.
I'm not sure specifically as there's not much information here. It could be a mystery related to Carson House's past, perhaps something like a long - forgotten family secret or a tragic event that took place there.
I'm not entirely sure of the specific real - story details of 'Fears to Fathom: Carson House'. It might be based on some local legends, haunted house tales or just fictional horror concepts created by the game developers.
