It is not a fact that vampires exist, but no, they don't have powers, they are the same as they were as a human, only they drink blood.
Magic powers. Vampires are boring, they are just the same as humans only they drink blood.
Vampires are fictional, but if you insist...They all react to sunlight apart from Count Dracula!
Vampires are considered works of fiction, and therefore has been created by imagination. This means that the powers they possess cannot be unimaginable.
vampire bats are nocturnal so that is when they are awake Vampires, if you go by the way they are in Dracula, can go out in day, but lose their powers (no sparkling). Because of this, they usually only go out at night when they are strong, but they can go out in day if needed. So they only feed at night when they can use their hypnotic powers.
Vampires are faster and strongerhan humans. Some might have powers such as knowing if someone is afraid.
Depends on the type of vampire you are taking about. many cultures have vampires each with their own powers and specialities.
In the end, there are 24 living vampires with a significant special power.

They're not dead but undead. Why they have powers differs per account, book or movie.
