Do you believe in witches that cast spells with pentagrams?

Firstly, I don’t think I believe in witches but I’m not positive. I’ve never given it much thought. But my daughter called and said her neighbor was “making the neighborhood a very evil place” and she was yelling about it. She said the neighbor, who even “looked like a witch” wanted to cast a bad spell on somebody. First this “witch” drew a pentagram in the dirt, then she wrote the name of the person on paper then burned another paper on top of the pentagram. I advised my daughter not to go over to that woman’s house. Is all this witch stuff fantasy or is there at least a little bit of truth to it ?
