Psychic Vampire

From Paranormal and Metaphysical Wiki

A Psychic vampire is a type of Otherkin that does not feed on blood, but on the life force of others. Just being around one can drain you of energy. If a person loses too much energy, they can get sick and display symptoms of fatigue, dizziness, or general weakness. Psi-vamps crave others' energy just as a sanguinarian craves blood. They sometimes go out of their bodies to find people that are sleeping and take the energy that the sleep is restoring in the person.
