What is demonic possession?

Demonic possession is when an entity called a demon takes possession of a person because they have weakened psychic boundaries and allow it. Demons take possession of a person when someone has a weak energy field.  A demon has never taken possession of me, but it happens to my family often enough because they have weak energy boundaries.  You see, only a Catholic bishop can do an exorcism on former or practicing Catholics who feel they are possessed.  Spirit possession is all about a spirit taking over someone’s physical body so that they can make them do things that are out of character or that they don’t want to do.
