Check out these top 10 unexplained paranormal phenomena.

Paranormal events are phenomena described in popular culture, folklore and other non-scientific bodies of knowledge, whose existence within these contexts is described to lie beyond normal experience or scientific explanation.

A paranormal phenomenon is different from hypothetical concepts such as dark matter and dark energy. Unlike paranormal phenomena, these hypothetical concepts are based on empirical observations and experimental data gained through the scientific method.

The most notable paranormal beliefs include those that pertain to ghosts, extraterrestrial life, unidentified flying objects, psychic abilities or extrasensory perception, and cryptids.
