According to
Dr. Housel, vampire legends date way back to 10,000 years ago to the Hindu god Kali. At least that is the first time that there is any written evidence. The stories probably go back even further than that. Kali is the goddess of life and death. She is called to Earth to stop these demons that have appeared. The problem is that every time a single drop of blood is spilled, a new demon appears. To defeat the demon, she has to suck every single drop of blood from all the demons to keep any more from appearing. She then uses her very long tongue and eats all the bodies as well. 4,000 years after Kali, the stories of Lilith appear. Lilith was Adam’s first wife and she was exiled for being non-submissive. She supposedly drank blood and ate flesh. The term Lullaby actually came from Lilith. A lullaby was sung to keep Lilith from coming.
Vampires are used to represent "otherness." Vampires, werewolves, and witches were all rolled up into one legend in the Middle Ages, usually in the form of a woman. Werewolves actually came from the myth of King Lycaon who was hosting Zeus for dinner. He decided to serve one of his own sons to Zeus to test and see if he knew what he was eating. He did and as punishment, he ripped off King Lycaon’s head and replaced it with that of a wolf. Originally, monsters were traditionally women, at least until the 1800s when Dracula was written. Bram Stoker based his stories on Vlad the Impaler, who was a real person. In the 1400’s, he would impale people on stakes to enforce the laws of the land. This is where the concept of a stake through the heart came from.
