You probably thought that there was only one vampire type out there. You’ll primarily come across the blood drinkers in popular media, but that doesn’t mean they constitute the only members of the vampire mythos. There are, in fact, a few types of vampires which are recognized by vampire enthusiasts.
Sanguinarians: As the name suggests, these are the blood drinkers. Blood replenishes their energy and is, as such, vital to their existence. Usually they have willing donors, but if they must go without for a while they will become weak and ill. While they can derive small amounts of nourishment from other sources, it is blood that they crave on a regular basis. Given that they extract the energy from blood, dead specimens are of no use to them.
Psi Vampires: Unlike the Sanguinarians, these vampires do not feed on blood energy but on life energy itself (some refer to it as prana or chi). Have you ever felt completely drained after having a conversation with someone? It is possible that this person is a psychic vampire. Many times, the individual in question is unaware of their abilities, but some are conscious of their needs and will actively feed off of anything from strong emotions to sexual energy.
There is some debate as to whether or not Psi Vampires are an entity unto themselves. Some people insist that there are only two main types of vampires, Sanguinarians and Psi Vampires. Others go further and classify Psi Vampires into sub-genres.
Elemental Vampires: Vampires who feed off the life force produced by the elements (wind, water, fire, air, earth).
Sexual Vampires: Better known as Incubi and Succubi, they sustain themselves using the energy created through sexual intercourse.
Empathic Vampires: This type of vampire generally feeds off of emotions, be they negative or positive. However, those which feed off negative emotions may actively seek to create a chaotic environment around them.
Hybrids: Quite a few Sanguinarians have the ability to feed off of psychic energy as well. Similarly, some Psi Vampires may be drawn to blood as it is rich in prana/chi. In most cases one feeding method is primary while the other is used as a supplement.
This is not an exhaustive list. If you ask ten different vampire enthusiasts, you’re likely to get ten different answers. Other vampire types that I’ve come across online are Otherkin, Soul Suckers, Dreamscape Vampires, Genetic Vampires, Inheritor Vampires, and Nightwalkers to name a few. Then there are the humans (Mortals) who have no supernatural vampiric characteristics but are either excited by blood-play or believe they need blood to survive.
Lastly, I’d like to mention the Immortals. This category is perhaps the most controversial and may also be the closest to the image of vampires which is popular in the modern media. They are thought to be gifted with supernatural powers and are depicted as being very tall and attractive. They are also known as the Ancients because of their longevity.
