Vampires are not real. That said, in stories, they can do whatever the author wishes.
Initially if you think about it, vampires were thought to live in castles in the middle of large untamed forests. These castles were extremely old and housed all sorts of creatures, spiders, bats, and such. And because the legends say Vampires are nocturnal, bats are as well.

No, vampire bats suck the blood of other animals, but they do not turn into vampires because there is no such thing as a vampire. They are mythological creatures and do not exist in reality.
