An unintentional psychic vampire is one that generally remains hidden. They are vampires who unconsciously feed on the psychic energies of others.
These vampires feed because they need extra energy to survive an illness. Unintentional psychic vampires are often much older than their victims, as illnesses generally effect older people. But, that doesn’t meant that children cannot be unintentional psychic vampires.
The victims never know that they are being fed from, which makes this type of vampire very dangerous. The victims may feel drained or tired, but otherwise fine.
Generally, these vampires are morning people, as they’ve fed the night before and have the extra energy in the morning.
