Dream About Driving And Lost

I was doing orientation for school and there was a cabdy store inside the libaray. I was in there for a while with my mom and sister and then I had to use the bathroom so I told my mom I'll be right back and she said ok. I went to look for the bathroom and when I finally found the bathroom there was no stall doors so I asked a big white man who was leaning up againdt the wall where the bathroom was and he led me all the way out the school. There was 2 cars in the parking lot and he told me to drive one and he will drive the other . We was in our own cars he told me go follow him and it was my first time driving a car but I had to use the bathroom so bad I didn't notice I was driving. Me and him was speeding up with the other cars then all of a sudden all the power in the state went out and cars went crashing into one another. I was able to control my steering wheel and lead my car into a forest. The white man followed me and crahsed into a tree. I passed ghe tree and slowed down. I went to check on the white man and he survived and wasnt hurt. I started freaking out becuse I was so far away from the school and my mom had no idea i had left. The white man led me to the bathroom and I finally got to use the bathroom. Then we walked back to the school which took about an hour. When I found my mom and my sistet they were busy having fun in a 3d room. However the school lights were out too
