As one of the most popular holidays, Halloween is a time to enjoy the intriguing mysteries of the supernatural and there's no better way to do that than through television. While the holiday definitely gives the horror genre a major boost in views, not everyone can handle it or enjoys watching it. Luckily for these viewers, there are plenty of non-horror supernatural shows. Across anime specifically, there is an incredibly wide spectrum of supernatural series. That being said, even non-horror anime can bring memorable moments of terror.
