hay.

Hay guys I like to ask if a human beings can turn to a vampire?

No, no human being can turn into a vampire, werewolf, or any other mythical creature. Those are creations of hollywood and are not real.

You cannot change your DNA by using magic. You are a human and you'll remain a human. Vampres, werewolves, mermaids and other such creatures are simply fantasy creations. They do not exist.
