In 2006, a physics professor at theUniversity of Central Florida wrote a paper arguing that it is mathematically impossible for vampires to exist, based on geometric progression. According to the paper, if the first vampire had appeared on 1 January 1600, and it fed once a month (which is less often than what is depicted in films and folklore), and every victim turned into a vampire, then within two and a half years the entire human population of the time would have become vampires.[107] The paper made no attempt to address the credibility of the assumption that every vampire victim would turn into a vampire.
In one of the more notable cases of vampiric entities in the modern age, thechupacabra ("goat-sucker") of Puerto Rico and Mexico is said to be a creature that feeds upon the flesh or drinks the blood of domesticated animals, leading some to consider it a kind of vampire. The "chupacabra hysteria" was frequently associated with deep economic and political crises, particularly during the mid-1990s.[108]
In Europe, where much of the vampire folklore originates, the vampire is usually considered a fictitious being, although many communities may have embraced the revenant for economic purposes. In some cases, especially in small localities, vampire superstition is still rampant and sightings or claims of vampire attacks occur frequently. InRomania during February 2004, several relatives of Toma Petre feared that he had become a vampire. They dug up his corpse, tore out his heart, burned it, and mixed the ashes with water in order to drink it.[109]
Vampirism and the Vampire lifestylealso represent a relevant part of modern day's occultist movements.[110] The mythos of the vampire, his magickalqualities, allure, and predatory archetype express a strong symbolism that can be used in ritual, energy work, and magick, and can even be adopted as a spiritual system.[111] The vampire has been part of the occult society in Europe for centuries and has spread into the American sub-culture as well for more than a decade, being strongly influenced by and mixed with the neo gothicaesthetics.[112]
