For those that are new to the idea of vampyrism, I will try to explain it a little more clearly.
First of all let's get some of the myths out of the way. Quite frankly when it comes to real vampyrism, myths play no part. Vampyres are human beings, they are not reanimated corpses coming back from the dead. Until science can prove there's such a thing as Immortality as in an immortal body, in my opinion immortals do not exist. There's no transformation into bats or other animals. Vampyres do not necessarily live a longer life then the average human who lives a healthy lifestyle or diet. Just like anyone else, they are prone to diseases. They do not have supernatural strength, sure there are humans that do have more strength then others, but when it comes to vampyrism, strength does not play role in deciding if one is a vampire.
Vampirism is a condition where the individual needs energy, prana, chi to in order to sustain themselves and remain healthy. This effects them, physically, mentally and some believe spiritually. The vampiric individual needs to take energy from another person. Some are psychic vampires, they feed from chakras or elemental energies, there are also emotional vampires or empaths, who feed on people's emotions. Sanguine Vampires need to take small amounts of blood from a person to get this energy, which ideally they use a donor for. Psi Vampires also have donors. If Vampyres do not feed regularly, they have been known to go through depression or sadness, have migraines, be easily aggravated and lose train of thought. Some of these "traits" can also be linked to illness and disease and that is why it's vital to go to a doctor and make sure everything checks out. When you can rule out any illness or disease, then it's time to take a look into vampyrism. No one can tell you, you are a vampyre. This is something you need to come to terms with and decide on your own. There's no master vampire who can awaken or turn/embrace you.
Vampyres are born this way, they go through an awakening, which is like a self discovery moment where they realize something is quite different about themselves. Some believe an awakening will happen between the teenage years or early twenties, however, there are people who have awaken later on in life.
There are some that play the role of the vampyre, they enjoy the esthetic's, the fangs, the clothes of the Gothic era and like to roleplay. There's nothing wrong with this. Some believe real vampyres are drawn naturally to the esthetics's however, not all have the fangs or content lenses and it's not necessary to have these things if you are truly vampyric.
In other words, a set of fangs does not make you a real vampyre.
A lot of times people will confuse a fetish with real vampyrism. A blood fetishist, is someone who enjoys the taste of blood. the sight and the smell, however on a deeper level they do not actually need blood to sustain their energy levels. Anyone can feed like a psy vamp, however, it's the same thing, if they do not need to feed on that energy to sustain themselves, they are not a vampyre.
I hope this clears up some misconceptions. This is just a basic idea of what vampyrism truly is.
