The incantation

In the late of fifties there was a famous author called ( Anis Mansour ) he wrote famous book I think it's name is two hundreds day around the world.
In his book he wrote incantation he heard it from witch from Africa to prepare someone died and ask him any question.
This incantation is about cage which covered by piece of tissue with pencil under this cage with paper.
Who will do that will say some words to ask this person to enter in this cage and write the answers about any question.
In this time many people tried to do that and my mother told me when she was young in University City she had colleague did that many times and my mother was witness about that.
My mother told me she watched this cage fly in the air and this pencil moves to write something and when they watch the paper they read the answers with bad writing
After that many strange things happened in this place like screams in the baths or hear something walks in passing which unseen and after that this colleague disappeared in unknown conditions.
The manager of University City asked many Sheikhs to read holy Quran to expel the ghosts from the place.
I think there were not ghosts for persons who died but there are Jinn which consider the partners for these people who died and they know everything about them so it's easy to tell these girls in this time many things about these people.

It's easy to ask Jinn to appear for you through many incantations but it's too hard to expel it again and if you don't be strong to control it sure this Jinn will hurt you with aggressive way.
