NO, THEY ARE NOT REAL!
I read a lot about them in comics when I was a young boy. I am just waiting for any vampire or witch to visit me.
All these are phanthoms and imaginations of the mind. I am not saying there are no supernatural powers. They are all over the world. But If one studies those powers critically you'll find some genuine scientific explanations that support their existence. Those super powers which remains mysterious to us are so because we do not understand the scientific theories that brought them into existence.
