It’s really cool that Dr. Betsinger lists some of the “causes” of vampirism such as “not being baptized, being born out of wedlock, being the first to die in a disease outbreak, committing suicide, even practicing witchcraft”.
If you really delve into the folklore, and I’m sure she has, some of the other ways to become a vampire include your corpse being carried out of your home feet first, your corpse being carried out head first, a cat or other animal leaping over your grave during the funeral, being born with teeth, having red hair and blue eyes, being a terrible person, or having a corpse that doesn’t decay.
At times, depending on where you were in central or eastern Europe, it seems like it was almost impossible to not become a vampire.
