The movie The Exorcist (w/Linda Blair) was based on a true story; with the exception that the victim of evil was a young boy, not a young girl. He had been using an Ouija Board which had inadvertently opened a door (vortex) to the other side. Through that door, anything evil can (and did) enter. Thus the beginning of his need for an exorcism. When anyone invites spirits into their world using this vehicle (the Ouija Board) or any other vehicle for contacting spirits they place themselves in unimaginable and imminent danger.  In addition to this, evil spirits commonly trick people into believing they (the spirit) are the spirit of a loved one who has passed and who the board user is attempting to contact.
