What is formerly known as "evil spirits" or "evil spirit possession" of certain people in certain situations may be actually Negative Energy entering their system. Where does this Energy originate? It may be the side effect of CK-E, or another energy source not produced by the Sun, but alien to Earth. It causes innocent people to commit violent acts, regardless of health or revenge or reasons explicable. It may be from pollution (Global Warming chemicals in the air) or from outer space.
