Let’s say that a person is wiccan or pagan, can they create something like a love potion to get them to fall in love with them?

Or, if someone upsets or angers them, can they cast a spell or use a potion or charm to affect the other person or to hurt or harm the other person.

What about dreams? Can they affect a person in that way?

I’m asking because I’ve heard that this is true. So, I’d appreciate honest answers. Thanks!
