Ghosts inhabit our collective awareness, literally haunting us with the possibility of their existence. The lingering spirits of the dead are common to every culture, although to be sure stories of their origin or the reason for their presence vary. Accepted wisdom states that ghosts are the spirits of people who died a violent death, or with some task left unfinished. More 'rational' minds aver that they are merely psychic imprints, a sort of supernatural photo-negative attached to a certain place. There is no real empirical evidence to back up either, or any, claims, but this does not prevent a thriving practice of ghost-hunting and paranormal investigation. [ Visit Website ]
