The new book Stolen Tongues was inspired by author Felix Blackwell’s fiancée’s unusual sleep disorder, reports The Press Democrat.

A year ago, Felix Blackwell, a 29-year-old Orange County native who now lives in Santa Rosa, was perusing the NoSleep forum on Reddit, a place for authors to share original horror stories with its 11 million readers. He was supposed to be working on research, but the stories demanded his attention. After a while, Blackwell felt compelled to join in the fun. He started a story that was fictionally based on his fiancée’s sleep disorder, and posted the first chapter. The rest is, as we say, history.
