The father of the vampire
Vampirisim is related to the inner and outer projection of a person's own denials and inhibitions. In particular, it reflects everything that is feared and repressed in the most instinctive part of the self. Inside vampire personalities, there is both a consciousness of lacking, and a desire to obtain that which they lack. These traits may stem from certain negative social conditionings vampire-types may have had to endure: mistreatment, lack of self esteem, and rejection, sometimes even from their own parents. One way to understand vampire people is to think of some sort of "monster" dwelling inside a person, forever unsatisfied, always in need of something external for survival. This monster cannot sustain itself or give anything to others.
In some ways, emotional vampires are like people who suffer from depression, alcoholics, or drug addicts. You will understand their mindset better if you think of those friends who are forever talking about their problems but never listen to yours. They might respond to something you've said by saying,"It's exactly the same with me," and go on to tell their story without really acknowledging your words.
Sexual vampires don't usually get in touch with their victims again. If they do so, it is only on their terms, and they refuse to explain what their true feelings are. And if they do come back, it is only for the sake of sex.
There is only one way to protect ourselves from vampires: recover the love for ourselves and focus on the light that lives within us, where there is no room or shelter for the shadows.
