I have been investigating paranormal sightings for many years, including unidentified flying objects and related incidents. Couple years ago during one of our Virginia MUFON meetings, about ten attendees along with myself and other field investigators, were individually interviewed by a table-hopping Washington Post reporter. Here's a statement I made that made his ears perk up: "on my many years of research I have noticed that if a witness observe a strange glowing sphere in their backyard, s/he would say it was a ghost but if the same sphere was seen 100 feet above the ground, they would probably have tagged it as an UFO ".
Should the right terminology be based on the height, shape or geographical location of these luminous manifestations? Who do you call if you see a large orb levitating off the lawn of the Arlington National Cemetery, hovers for a moment then flies up to the top of the Washington Monument prior to disappearing above the clouds...a ghost hunter, a UFO hunter or Jack Daniels?
My colleagues and I have discussed this subject on many occasions, the similarities between these apparitions: how they metamorphosize into different shapes including humanoid, how they can pass through solid objects, how they affect electronic equipment, how they communicate with their witnesses or victims - telepathically, and how they prefer to make their appearances in the middle of the night under the cover of darkness. Something to ponder upon.
