Ghost Paranormal is an umbrella term that is used to refer strange happenings or experiences that either lacks or has no obvious scientific explanation. In terms of the science of parapsychology, the term Ghost Paranormal is used to describe the potentially psychic phenomena of extra-sensory perception, telepathy, psycho kinesis, ghosts and haunting. The term is also applied to talk about the UFOs, some of the creatures that fall under the scope of crypto zoology, purported phenomena surrounding the Bermuda Triangle and various other non-psychical subjects. Stories that relates to Ghost Paranormal phenomena are very common in popular culture and folklore, but some organizations such as the United States National Science Foundation or the USNSF have also stated that mainstream science does not support Ghost Paranormal beliefs.
