What Is An Apparition ?
"An apparition is defined as the supernatural manifestation of the soul of a decease person or animal, typically referred to as a ghost. Apparitions are visual experiences. Throughout history human beings have seen ghosts. Despite research efforts there is still very little known about apparitions. They are the most compelling part of the supernatural field. The one thing that is known about apparitions is that no two are exactly alike. They are as complex and diverse as each living person. Every apparition will have it's own cause, origin and meaning. It's up to the ghost hunter to analyze the facts of each case and develop solid conclusions. To help the ghost hunter acquire a better feel for the kind of apparition they are dealing with, apparition categories have been created. You will find that most apparitions will fit into at least one of these
categories or share characteristics with a couple different categories". (http://www.ruhaunted.com/)
