Dream of kids, children, murder, mother

Driving normally with my children in the backseat. Stopped at a store and left kids in car. When I came out, there was a man sitting in the driver seat, my seat, who was going to hurt either me or my children, like some psycho. I fought him out and drove away fast to escape. My husband murdered his friend's sister and I witnessed someone murder that same friend's mother, throw her in a trash can, and light her on fire.
