Ghosts are those in the spirit world who wish to hang around the earthly plane a while.  Some make noises.  Some move objects.  It is the fear of the unknown that causes humans to fear ghosts.  What if you knew that ghost was grandpa?  If not your grandpa, then someone else’s, who is just trying to make a point?  You have been programmed by your horror movies to immediately think the worst when you hear the word ghost.  Think instead of your romantic movie with the same name (“Ghost”), and never forget that the underlying fabric of all life is Love.  Some beings remain here longer than others out of their deep and enduring love.  Return it in kind and help them by doing so.  All are so very loved.
