Graveyards are a favorite place for this type of hunting. But sightings have been reported at churches, schools and many older buildings. It has been said that many church members like to return to their church and keep a watch over it. A ghost investigation would involve going to the place of a sighting and recording by video any forms that appear or sounds, and the temperature of the room or surrounding area. If something is suspected and the ghost is causing trouble then the investigator would assist in trying to make the ghost move on and leave the house or area.
Many people believe that there are two or three types of ghost.
They believe that one type may not know it's dead and they look just like the person they were while on Earth. They could be good or bad, still having the same personality. Another type would be a ghost who never was a human to begin with but a demon from Hell and considered quite risky. Overall the general population does not believe in ghosts at all. Today the commonly accepted theory is that any such type of activity represents the unconscious mind trying to find a way to let off a little steam.
