Psychic Vampires
Psychic Vampires are humans who have some telepathic ability and use this ability to draw the life force from others.
They come in two types, Intentional and unintentional.
The first type actively seeks out victims with whom the Vampire will attempt to interact in such a way as to provoke strong emotions, sexual intercourse is the most common. The Psychic Vampire will then use the time when the victim is at his or her most vulnerable to absorb the mental energy emanating from the aura. Other Psychic Vampires prefer to attack victims whilst asleep, often causing vivid nightmares upon the emotions of which the Vampire feeds. The victims will feel drained of energy and inexplicably tired after an attack, however death from Psychic Vampire attack is rare. Outwardly the Intentional Psychic Vampire is a normal, ordinary human being although many choose to become haemavorous as well, imitating the more common human blood-drinkers described in previous post. Psychic Vampires are not immortal but are victims, nor do they suffer from the downfalls of True Vampires such as allergy to sunlight or allium.
Unintentional Psychic Vampires feed in precisely the same way as their more malevolent cousins. The only difference is that they are completely unaware that they are doing it. They will feel refreshed after sex whilst their partner lies in a stupor. They are morning people, having fed while they slept on other members of the household who will complain that their housemate is far too chirpy in the morning.
