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.
