It is sad that folks immediately jump to the false conclusion that ghosts are evil or demonic simply because they do not understand them. Ghosts are NOT demons. First, take off your religious rose-colored glasses and view the events without religious dogmas and fears. Ghosts are people without bodies. They have intelligences, emotions, personalities and attitudes, just as they did when they were living.
Ghosts are people without bodies, complete with their attitudes, personalities and emotions.
If they were happy campers in life, they will be happy campers in death. Ghosts are NOT fragmented souls cursed to roam the earth. This is an outdated philosophy by ill informed ghost researchers who relied upon Ouija boards and seances for their information. Just as some people are loners so too are some spirits. Most hauntings are by more than one ghost, often several.
