h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I don't know if vampires are real. But I have heard stories about them. I never personally encountered a vampire but I think my friend, dad did. You know how there's a myth that vampires can change into bat's. Well one night I was sitting on my front porch and my friend's dad was walking home at night and he just suddenly got attacked by four bats. They were biting at him. This really happened it's not a joke. That made me wonder could these bats really be vampires turned into bats or just bats and I simply let my imagination run wild. Because you know vampire bats are not suppose to attack people and where I live there wouldn't be any vampire bats to be found. If anyone else has had a vampire encounter or experience post it. I would like to read about it.
