This is the truth about chi vampires.
People that refer to themselves as "chi vampires", aren't actually vampires. They are people that have been brainwashed in to believing that being able to take Chi is what makes some one a vampire. While in truth any normal person can learn to take Chi, and any normal person can learn to use psychic abilities. Any person that actively uses psychic abilities and Chi, will for obvious reasons use Chi quicker than their body produces chi energy. In effect this will result in them feeling a need to draw additional Chi from outside sources, until they learn ways to make the extra Chi on their own. This side effect that would seem obvious to most people, is what makes some people think that they are "chi vampires".
Chi vampires aren't vampires, and they are far from being real vampires. These wannabe vampires go by other terms that are based on whatever source they prefer to draw the energy from as well. Such as psychic vampires, energy vampires, emotional vampires, elemental vampires, astral vampires, and sexual vampires. Basically just (fill in the blank) vampires. All of which are just variations on the term chi vampires, but more specific in their own weak attempt to give themselves a title. Ironically while these wannabe vampires claim that they don't want to be associated with vampires, due to them admittedly having nothing in common with vampires. They refuse to drop the word vampire from the titles that they give to themselves.
So far I have only been referring to the people that call themselves chi vampires, due to their own false beliefs. Assuming that they even actually believe themselves to be some chind of vampire in the first place. There is another group of people that refer to themselves as chi vampires as well, these people follow it as a religious cult that finds it's basis directly from satanism.
The first type mentioned on this page are not satanists, they come from every religion including christianity and like real vampires they shouldn't be classified in any way as part of the satanism based religious cult that the second type of self defined chi vampires are a part of. Though people from both groups of chi vampires (wannabe vampires), as well as real vampires with enough practice do learn how to take enough Chi from a normal person, to cause drowsiness and in some cases make them go to sleep. Being able to take Chi from some one, even in those amounts does not make a person a vampire, anyone can learn how to do it. Go to this page to learn how to take Chi, as well as how to do other psychic abilities.
Both the religious cultists and the ones just following their beliefs are deluded enough to believe that the Chi they are taching is the persons life energy and or soul. Also like religious cultist chi vampires, both types of people that call themselves chi vampires believe taching that Chi makes them a vampire.
The religious cult chi vampires, like satanists believe that they are taching a persons soul. The religious cult chi vampires, like satanists believe they are taching those souls and giving them to a religious deity. The religious cult chi vampires, like satanists believe that in return this deity gives them new abilities as a gift in return. The religious cult chi vampires, like satanists also believe that doing this makes them some thing special instead of just the psychotic little deluded freaks that they are.
None of the people that call themselves chi vampires are real vampires, nor do they have any idea what it's like to be a real vampire. Real vampires can do some things (that normal people can't do) so easily that it happens on accident, and they have to make a conscious effort to stop it from happening, that these wannabe vampires (aka chi vampires) are so far from being able to do, that they don't even believe it's possible for a real vampire to do it.
Real vampires are a race, real vampires are not a religion, set of beliefs, a subculture, or a cult. Real vampires exist due to a genetic anomally caused by an endogenous retrovirus or genetically obtained through birth just like any thing else that is genetic. You can't become a vampire through a spell, through taching Chi, or by reading a website or a book. The only way to be a vampire is by either being born a vampire, or getting a real vampire (not a chi vampire) to change you into a vampire through an exchange of blood.
