There can be no such thing as ghosts...that being spiritual parts of people left over when they die.
The Bible is clear on this;
(ECCLESIASTES 9:5-6) �For the living are conscious that they will die; but as for the dead, they are conscious of nothing at all, neither do they anymore have wages, because the remembrance of them has been forgotten. 6�Also, their love and their hate and their jealousy have already perished, and they have no portion anymore to time indefinite in anything that has to be done under the sun.�
But who in the spiritual world is aware of what is going on?
It is Satan, and he has the ability to cause people to see things and make it look like it is caused by dead peoples ghosts...which the bible says cannot exist.
Believe the scriptures and believe in demons...they DO exist.
(MATTHEW 8:28-29) �When he got to the other side, into the country of the Gad�a�renes′, there met him two demon-possessed men coming out from among the memorial tombs, unusually fierce, so that nobody had the courage to pass by on that road. 29�And, look! they screamed, saying: �What have we to do with you, Son of God? Did you come here to torment us before the appointed time?��
Even the demons know that Jesus is the SON of God, NOT God himself.
