A lot of the information out there on human vampirism actually isn’t disinformation. At the same time, though, vampirism is not human.
Vampirism is a process, happening in nature, naturally, exchanges of energy. When you have sex, you are being vampirized, and vampirizing at the same time. When you are eating food, you are essentially vampirizing the dead animal or plant, claiming its power as yours. Any chi that’s left, and in the cases of fruit and vegetables, potential energy.
The same way babies tend to have more energy than average grownups, because less of their natural energy was used up, the same applies to fruit. The act of vampirism, becoming a predator, even a devourer on higher levels, is being both consciously aware of that interplay of energy and exploit it.
I second what Mephistor and thatrandomguy have said. I rely heavily on breath as a medium for the exchange of energy, but as time goes by, I’ve noticed it’s a physical crutch I need to do away with, so while I would recommend beginners use their breaths(inhalation=in, exhalation=sealed/grounded), I would also recommend they learn that they don’t need it and once they’re good enough just do it with their minds and will.
Another crutch that can help you, but that you will eventually have to unlearn is touch. The Left Hand pulls energy, so just place it on someone’s shoulder, in a handshake, or hug, and pull. Transcend that, by feeding from eye contact, making people profoundly uncomfortable, and straining their attention. And then transcend that by going with breath alone with the tendrils(what thatrandomguy describes) then transcend even that by just ‘‘willing’’ it into yourself.
It’s a very fun path, and if you need any advice, have any specific questions there are many individuals here willing to help. It’s also pretty universal, in that it helps you learn energy work which is important for everything in this line of work.
As for good books that teach vampirism, I learned my stuff not just from E.A. and his instructions in Works of Darkness, but in a couple of other places.
Namely, Ardeth:The Self-Made Vampire, The Psychic Vampire Codex, the Sanguinomicon, Uncle Chuckie, especially psionic warfare and supervillain, articles on the Internet everywhere, imagination, and talking to other vampires.
Also, about your descriptions of vampires, it is fairly Hollywoodish, as Mephistor said, but not totally unreliable. The vampire is a black magician, he/she is powerful. Since we feed on the astral plane, where we can easily shape shift and fly, those abilities are attributed to us, are astral(physically they are hard though not impossible), much like the invisibility, and so many other things. THe hypnotic and mind control stuff is all very natural and possible,and the eternal youth…
Well you can maintain vitality for a long time, look much younger, etc. though atm not sure how you could live forever. I know it’s a goal for a lot of people, though, and I do believe immortality, in a variety of different ways, is indeed possible, especially with enough power.
