Please help me decipher this frightening dream- pt. 1

*I had a dream that my grandmother was dying and she practiced roots/witchcraft. She had demons inside of her and she knew she was dying so she wanted to take the demons out of her and put them inside either me or my kids. So she was trying to do anything she could to get me to bring my kids over to her house. As me and my kids neared her house, the sky kept getting darker and darker as though it was nightime but it was day time. The main street I had to turn off to get to her house was blocked by the police and they were turning people around telling them not to go down the street towards my grandmothers street. And as I looked down the street every street closer to hers was darker and darker and I could feel an evil presence. As I turned down the street towards my grandmother's, I felt worse and worse about the evil presence so I turned around. When I came back to the main street the police officer stopped me and asked me "didn't you hear me tell you not to turn down the street" and I told her no I thought she was talking to the other cars. The officer then says "you're special cause every other car that went down there after we told them not to didn't come back" and then she walked off. I drove off in my dream going back home and then I woke up.
