What does my dream mean?

in the dream i'm at a church.. it looks kinda familiar but the location isn't in a place i've ever seen. the church doors are open and it looks like a touristy area where people just go to look around. i was standing outside the church in the dream and i noticed this woman kneeled down in front of the church with a vase looking object in her arms and she looked like she was praying or performing some sort of ritual with it and the weather turned bad after that.. i think maybe a tornado was coming and i looked back over to her and she looked up to the sky and looked back at me and smiled with an evil glint in her eye and i realized that she made the bad weather happen. the dream ended after that... Any idea what this could mean?
