After spending some time in the Bulgarian mountains I now believe in Dracula!

The following is from - http://vampires.monstrous.com/bulgarian_vampires.htm

Bulgarian beliefs concerning undead vampires are quite varied. Bulgarian names for an undead vampire include: Vampir, Vorkolak, Ouber, Ustrel, …

The pure Bulgarians call this being by the genuine Slavonic name of Upior; the Gagaous (or Bulgarians of mixed race) by that of Obour which is Turkish; in Dalmatia it is known as Wrikodlaki, which appears to be merely a corruption of the Romaic. It seems that the names vampir and obour as used in Bulgaria often mean the same thing.

In one account from Bulgaria translated and quoted in The Darkling by Jan Perkowski, the vorkolak is said to be the soul of an outlaw who perished in the mountains, or in the forest, or along a country road, and whose corpse is eaten by crows, wolves, or some other such scavengers. This soul cannot enter heaven or hell, and so it remains on earth. This vorkolak haunts the place where he was killed. At night, this spirit strangles and drinks the blood of anyone who comes by. The way to rid a place of a vorkolak, is to erect a cross, bless water, and hold a church service at the spot where the outlaw died.

In another account from Bulgaria quoted in the same book, a vampir is a corpse which returns from the grave. A person who died a violent, unnatural death or whose corpse was jumped over by a cat before burial becomes such an undead vampire. (This belief is found all over Eastern Europe where there is belief in undead vampires.) In a case mentioned in this report, a man became a vampir as the result of a fatal fall from a roof. The bones turn to gelatin at first and during the first forty days after burial he performs mischief such as releasing animals from their pens, scatters house hold items, and suffocates people. If not destroyed within the first forty days, the vampir developes a skeleton and becomes even more fierce. At least during the first forty days, the vampir can be destroyed by a Vampiridzhija (a professional vampire hunter) or devored by a wolf. The report doesn't make clear what it takes to destroy the vampire after he develops a skeleton.

A bit of a laugh, for sure, but I wouldn't be sleeping outdoors up here! lol Wooooooooooooooooo! lol
