First of all you have ghost "hunting" and ghost "investigation". Ghost hunting is going to a location that may or may not be haunted and trying to capture them on video and/or photos. Ghost investigation is going to a known haunted place and recording data (video, photos, audio and temperatures), taking notes, interviews and other evidence to prove/disprove the haunting and existence of ghosts. The more experienced hunters investigate and document reports of ghosts, hauntings and paranormal activity, where as many of the amateur ghost hunters are just out to have fun. I believe that most teenagers that go out on Halloween night to ghost hunt in the graveyards, haunted bridges and buildings are out to have fun and get scared, not to really be considered "investigators". My nephew Aiden has been doing it for several years now with his friends and they love it. Me, I'm not one to purposely put myself in a situation where I'd be scared half to death, so ghost hunting is definitely not on my list of things to do! Today ghost hunting is becoming increasingly popular with amateur ghost hunters, in part due to the easy access of information on the internet and all the current television shows about hauntings. Since the whole spirit of Halloween revolves around the souls of the dead returning to earth to haunt the living, Halloween night is considered a prime time for hunting ghosts. The definition of a "haunting" is a recurring presence of a ghost, demon or similar supernatural being at a specific place. Old houses, hotels, restaurants, pubs, prisons, cemeteries and graveyards are the most common haunted places. So this year on Halloween night get your friends together and go out ghost hunting. Who knows, you might just see one of the "souls from the dead" - let's just hope it's a happy soul! Me, the only ghosts I want to see on Halloween night are the "souls of the living" in a ghost costume ringing my doorbell and saying trick-or-treat!
