So are there ghosts?
There are, however, many theories to explain the thousands upon
thousands of documented experiences that people around the world
have had since the beginning of recorded history. Ghosts and
hauntings seem to be a relatively common part of the human
experience. And there appear to be several types of ghosts or
hauntings, and more than one theory may be needed to explain them
all.
Dead people
The traditional view of ghosts is that they are the spirits of dead
people that for some reason are "stuck" between this plane of
existence and the next, often as a result of some tragedy or
trauma. Many ghost hunters and psychics believe that such
earth-bound spirits don't know they are dead. Veteran ghost hunter
Hans Holzer says, "A ghost is a human being who has passed out of
the physical body, usually in a traumatic state and is not aware
usually of his true condition. We are all spirits encased in a
physical body. At the time of passing, our spirit body continues
into the next dimension. A ghost, on the other hand, due to trauma,
is stuck in our physical world and needs to be released to go
on."
Ghosts exist in a kind of limbo in which they haunt the scenes of
their deaths or locations that were pleasant to them in life. Very
often, these types of ghosts are able to interact with the living.
They are, on some level, aware of the living and react to being
seen on the occasions that they materialize. Some psychics claim to
be able to communicate with them. And when they do, they often try
to help these spirits to understand that they are dead and to move
on to the next stage of their existence.
