Magnetic vampirism is a form of psychic vampirism that entails sucking the life force out of one person by another.
Many magnetic vampires unconsiously prey on sensitive people. Some even prey on animals, such as pets. There are reports of magnetic vampires who find they cannot keep pets alive, as for unknown causes, the pets die.
People often feel loss of energy when around certain people (the vampire) and after prolonged exposure can become ill and die.
