There is no one answer to the question of how one may know if something is considered supernatural. This is because there is no one definition of supernatural that is universally agreed upon. For some, supernatural may refer to anything outside of the natural world. For others, supernatural may only refer to phenomena that cannot be explained by science. There are numerous supernatural phenomenons that can befall humans, from paranormal activity to supernatural visions. It can be difficult to determine if something is supernatural, but if someone is claiming that an event is supernatural, it is important to ask them to explain what they mean by that.
