Leaving the matrix

I am at my grandmas house, mom and grandma are outside talking, my sister leans out from the living room window and tell them that there is someone behind them, we look and it's a young girl in a yellow and black uniform. Then we hear more people and look to the outside of the fence and there's a few more girls in uniform riding horses. Me my sister and grandma get into a van while my mom drives it, I can't sit in a seat properly for some reason so I'm sprawled on the floor with my lower half on the seat, and I have quarters that fall and roll around because my mom can't drive right. I suddenly notice that grandma is gone, I ask my mom where did she go, my mom says she was dropped off at the store to buy my sister stuff. I also then notice the van door on my side is wide open and my mom is driving pretty fast, I see her wallet is by me with her important cards and stuff, I think I hope none of her stuff fell out, but I grab her wallet and hand it to her.
