Strange phenomena refer to unusual events or occurrences that defy normal explanations. These can include natural occurrences like ball lightning, which is a rare and poorly understood atmospheric electrical phenomenon, or mysterious sounds that have been reported in various locations around the world, often without a clear source. In addition to natural events, strange phenomena can also encompass human experiences, such as pareidolia, where people see familiar patterns, like faces, in random objects. Other examples include UFO sightings, which have sparked curiosity and debate about the possibility of extraterrestrial life.
