Demonic possession is something which has been around for quite some time. There are different types of possession which can take place. Demonic possession is actually quite rare.
There are forms of oppression and infestation which are lesser versions of a full possession. With so many reported cases of someone being possessed by the devil or from some demon, it is difficult to believe what might be a hoax or something which may have actually happened according to some people.
For example, an American woman actually levitated demonstrating her powers which were psychically based if not hypnotic. This same woman spoke foreign languages and unknown to her, she was under some type of demonic possession. This same woman who remains unnamed was involved with certain satanic groups. She was later observed by a number of people including priests, psychiatrists and nuns. By their observations, this same lady actually levitated six inches from the ground, objects moved across the room and flew off shelves.
A Dr. Richard E. Gallagher documented this case. Richard is a board-certified psychiatrist in a private practice located in Hawthorne, New York. He also is an Associate Professor of Clinical Psychiatry at New York Medical College.
It is extraordinarily rare for someone to actually be possessed by the devil itself. An actual attack upon a person can linger or suddenly fade away from an exorcism which was performed by a person of great religious faith. Demonic possession starts suddenly and a person will start acting rather odd unlike themselves. Their personality might not change suddenly, but it there will be tell tale signs of change.
This same woman known as “Julia” who was observed was a true Satanist in her life and thereby demonstrated extraordinary occult abilities. When someone returns to their state of mind while being possessed, they have not recollection whatsoever of what actually happened to them. Often the person will exhibit trance-like states when approached by someone.
Descriptions of demonic possessions often include erased memories or personalities, convulsions, “fits” and fainting as if one were dying.
