Do vampires actually heal quickly like most people write about in books? If so, how is it possible for them to heal quickly? I think it would have something to do with the blood but I am not exactly sure how. But then again I don't know if vampires do actually heal quickly. So is it fact or fiction? - Elizabeth Kolodziej
We must first examine what a vampire is before attributing human qualities to what is in essence a demonic predatory manifestation capable of masquerading as a dead person to the point of materialisation through quaffing warm blood by which process the corporeal shell is seemingly nourished and sustained. Ultimately, however, the vampire is a supernatural being, so to ask if such creatures "heal quickly" is irrelevant. They already possess the ability to metamorphose, which permits them to change into virtually anything, including other creatures and even mist.
To rely on works of fiction, particularly recent inventions that pay no heed to tradition and folklore, serves only to take you further from the answers you seek about these hideous demons. I would recommend such works as The Vampire: His Kith & Kin and The Vampire in Europe by Montague Summers as a good starting point for anyone wanting the kind of information you are seeking. There is also my own The Vampire Hunter's Handbook.
