dreaming about numbers

In my dream my brothers and I are younger and my mom makes us guess numbers that have to do with aeroplanes. If you guess the wrong number the people on the planes die. My brothers guess different number but are both some how right. I guess wrong so hundreds of people die. My mom then tries to kill me. Next thing it shows is me and two friends are running through a desert that has abandoned cars and a few houses trying to get away from the cops and my mother. This dream makes me sleep walk and get physically sick such as puking.
