Some modern vampyres are simply blood drinkers. They do not attack and drain victims, but obtain blood in a varity of legal manners (such as from themselves, local donors or a source at a blood bank).
In such cases, the consumption of the blood has little to do with any on going relationship to the source of the blood. It, like food, is merely consumed. Often times, modern vampyres, report getting a psychological or sexual high from drinking blood.
Most vampyres of myth/legend are not resurrected corpses, in numerous are disembodied demonic spirits.
Once it is settled that "vampyre" covers a wide variety of creatures, a second problem arises. As a whole, the vampyre themselves are unavailable for direct examination. With a few minor exceptions, the subject of this volume is not vampyres per se, but rather human belief in vampyrism.
Here is a poem by the guy R Campbell Thompson
Spirits that minish the heaven and earth,
That minish the land,
Spirits that minish the land,
Of giant strength,
Of giant strength and giant tread,
Demons (like raging bulls, great ghosts),
Ghosts that break through all houses,
Demons that have no shame,
Seven are they!
Knowing no care, they grind the land like corn
Knowing no mercy, they rage against mankind,
They spill their blood like rain,
Devouring their flesh (and) sucking their veins.
They are demons full of violence,
Ceaselessly devouring blood.
Blood in the biblical tradition
But you must eat the flesh with the life, which is blood, still in it. And further, for your lifeblood I will demand satisfaction and from a man also will require satisfaction from the death of his fellow man.
From Genesis (God talking to Noah)
From Lord Byron's
But first, on earth, as vampire sent,
Thy corpse shall from its tomb be vent,
Then ghastly haunt thy native place,
And suck the blood of all thy race.
They’re from thy daughter, sister, wife,
At midnight drain the stream of life,
Yet loath the banquet which perforce
Must feed thy livid living corpse.
Thy victims are they yet expire.
Shall know the demon for their sire,
As cursing thee, thou curing them,
Thy flowers are withered on the storm
Hematomanania is a blood fetish sexual pleasure and other psychological needs of persons with this condition are met by the regular consumption of human blood, occasionally in conduction with the eating of human flesh
Gypsies believed that some vampyres have insatiable sexual appetites and will return from the grave to have sex with their widow or a young woman of their choosing. The vampyres continued visits could lead to the woman becoming pregnant.
The product of such an union, usually a male, was called a dhampir. It was believed that they had unusual powers for detecting and destroying the vampyre.
Most vampyre folklore happened after people dying from a lingering disease. After they died, neighbors dug up the corpses and observed a variety of unusual conditions, all signs of skin had a ruddy complexion and the hair and fingernails had continued to grow.
Fresh flesh had appeared as the outer layer of skin had peeled off. Blood was present around the mouth and in the body when it was cut or punctured. There might be a sexual erection on the bodies of the males. If staked, the body reacted as if in pain.
An incubus is a male demon that stalks a woman by coming into her room and forcing her to have sex with him. A succubus is the female form of the demon that goes in and forces a man to have sex with her.
By New Manson Family song was
I have existed for centuries
Living in castles built of your fears
And from behind this mortal mask
I carry out this deadly task
In order to revive myself
I plunge into the stream of life
That drains into the scarlet seas
And holds the red wine of immortality
On swift sail flaming
From storm and south
He comes pale vampire
Mouth to my mouth
La Bella Morte The Vampire
Her eyes have feasted on the dead,
And small and shapely in her head,
And dark and small her mouth, they said,
"And beautiful to kiss,
Her mouth is sinister and red
As blood in moonlight is."
This comes from
Temple of the Vampire
I am a vampire.
I worship my ego and I worship my life, for I am the only God that is.
I am proud that I am a predatory animal and I honor my animal instincts.
I exalt my radical mind and hold no belief that is in defiance of reason.
I recognize the difference between the world of truth and fantasy.
I acknowledge the fact that survival is the highest law.
I acknowledge the Powers of Darkness to be hidden natural laws through which I work my magic.
I know that my belief in Ritual and fantasy but the magic is real, and I respect and acknowledge the results of my magic.
I recognize there in no heaven as there is no hell, and I view death as the destroyer of life.
Therefore I will make the most of life here and now.
I am a Vampire.
Bow down before me.
