The intentional psychic vampire is one that should be feared the most. This vampire cannot be destroyed by any physical means and they tend to attack on out of every five people. Luckily, the attacks are rarely fatal; the victim is drained of energy on purpose by the vampire.
Once the vampire is able to master feeding off the energy, they move on to astrally projecting themselves and feeding off those who are sleeping.
Eventually, these vampires die, and when they do, they become earthbound entities that continue to feed off the living by using psychic energy that they absorb to keep their astral body from decaying.
