People that learn don't say everything in book so pretty much there is the Psi vampires and that's all I know is real but none of the blood drinkers are real (Expect the kind that do it because its life force and not because they find it fun or to turn you into a vampire which are fake)
So you're saying books don't teach anything. Real history is being taught by book not by modern tv's remember. Books are the first which we came to teach not modern technology.
I believe books are very important. Where do you learn your learnings from? It is very unbelievable that you learned all you know through some sort of "Higher power" without consulting any books of the matter. It would be like summoning a demon without knowing the right conjurations.
Vampires do not, in any means, exist. A psychic vampire is not a vampire at all. Vampire cults may exist, but living the lifestyle of a "vampire" is not the same as being one. Anyone that claims to be an actual vampire is most likely being a liar and a fluff. The original myths about Vampires were either witches that were screeching half animal evil women or animted red-headed corpses that sucked blood. The Vampires in 16 and 1700s are left over superstitions from the witch burnings. Then in the modern century, people romanticized them and wanted to be indestructable sexy beasts of the night. Attractive pale skinned humans are pure fantasy invention.
Vampirism is actually real. However it does not by any means provide the longevity, the need for blood, that pretty ivory complexion, sparkles, or innate healing ability.
Vampirism does not make you immortal.
Vampirism does not give you sexy red eyes.
Vampirism is not an ideal method of living I assure you.
It's a form of cannibalism because you remain human by all means. Drinking blood makes you sick. You turn yellow, this disease is called Jaundice. You puke your gastric contents regularly from lack of proper nutrition. You lose weight because of this. You become frail and weak. You attain a sensitivity to the UV rays but not because you're some creature of Hell, it's because your skin is literally deteriorating from the diseases and illness you've contracted. You begin to look older because the lack of hydration makes your skin sag and lose color.
