Why are cemeteries haunted? Unless someone was murdered or hung there,
there really isn't any reason why they should be haunted. If a ghost
knows it's dead, why would it choose to hang around in a cemetery all
day when it could go somewhere else? And if it doesn't know it's dead,
then it should stay around the place it lived. One possibility is that
it's a residual haunt and not an intelligent. The energy from all the
people who come to the cemetery to grieve gets imprinted onto the
environment. If the ghost knows it's dead and is free to go anywhere it
wants, it's also possible that it could just be visiting its grave. But
traditionally there is no reason why cemeteries should be haunted,
unless someone died there.

There is another theory involving ley
lines, which are hypothetical earth energies that align a number of
places of geographical interest such as old cemeteries, churches,
ancient monuments and megaliths. Some believe that our ancestors could
sense these energies better than us, and they subconsciously placed
cemeteries and churches on these places to try to neutralize the "bad"
energy. This, according to the theory, is why a lot of cemeteries and
churches (places that are supposed to be holy) are haunted - because
spirits are drawn to the energy there, which they use to manifest. One
of the problems with that theory is, as has been said in previous
entries, ghosts don't draw energy from batteries, appliances, and the
environment to manifest. Many researchers believe that ghosts ARE some
kind of energy, they have their own. Also, ley lines haven't been
proven. Skeptics say that the so-called ley lines could be the product
of ancient surveying, property markings, or commonly travelled pathways.

Before
you investigate a cemetery, you should research the history to find out
if anyone died in it, because otherwise it's probably not haunted.
