I only heard that The Romanians actually called vampires "Strigoi" and are seen as ghosts, undead, immaterial things; they are usually a recently buried member of the family, who returns to haunt his relatives and drain their life forces, sometimes in dreams. In order to bring peace to the family and to the undead itself, some "rituals" need to be performed.
This according to a story I found online by Massimo Polidoro.
Pretty interesting stuff!
