Are vampires real? If you define them simply as creatures who drink the blood of other creatures, then real vampires do exist, and they are plentiful, both amongst humans and other animals in the wild.
But what of other aspects of vampire lore, like the fact they are undead creatures, that they are immortal, that they have sharpened incisors, the ability to shape-shift, that they can beguile or otherwise hypnotize people into bending to their will, or the idea that they cast no reflection? While many of these characteristics are the stuff of fantasy, as you will see in these true stories of real-life vampires, many are all too real. Other instances on this list do not necessarily demonstrate real vampires, but are instead documented "cases" of vampirism in the history books.
Also known as Blagojevich, this man is one of the earliest examples of vampirism and the so-called vampire hysteria that plagued Europe in the 1730s. Moreover, Plogojowitz's story is credited as founding many of the most commonly recognized aspects of vampire folklore.
It seems likely that, through the passage of time, this tale has taken on elements of the fantastic, confounding the truth of the situation, but it is nonetheless an enjoyable and chilling tale. To summarize as concisely as possible, it is said that weeks after dying and being buried, Plogojowitz was seen walking around his village, looking healthy and decidedly not dead.
His wife even attests to having had a visit from her husband, requesting his shoes. Around this same time, several villagers began suffering a bizarre 24-hour illness and dying. All of them swore that Plogojowitz came to them in the middle of the night and throttled them in their beds. His son also reported seeing his father in their kitchen - then he too died under mysterious circumstances.It was finally decided to exhume Plogojowitz's body. Upon doing so, the villagers discovered the man alive and breathing in his coffin. They immediately staked him through the heart and burnt his corpse, after which the nightly terrors and sudden deaths instantly stopped.
While human attacks are especially rare (apparently, only when they are starving), lampreys are fish neither man nor woman would ever want to encounter. These animals use their jawless mouths full of razor-sharp teeth to latch onto prey and drain them of their blood as they swim.In other words, lampreys are essentially the vampires of the sea.
