From Wikipedia:
Paranormal is a general term that describes unusual experiences that lack a scientific explanation,[1] or phenomena alleged to be outside of science's current ability to explain or measure.[2] In parapsychology, it is used to describe the potentially psychic phenomena of telepathy, extra-sensory perception, psychokinesis, ghosts, and hauntings. The term is also applied to UFOs, some creatures that fall under the scope of cryptozoology, purported phenomena surrounding the Bermuda Triangle, and other non-psychic subjects.[3] Stories relating to paranormal phenomena are found in popular culture and folklore, but the scientific community, as referenced in statements made by organization such as the United States National Science Foundation, contends that scientific evidence does not support paranormal beliefs.[4]
