Moving in formation

I had the same dream I have been having last night about being in my grandads old Reliant K Car with my mother and sister. This was the 6th night in a row I have had it and the 8th time in the last 10 nights. The dream started as always where I am alone in the Reliant buckled to the center of the tan vinyl front bench seat. Around the time I had finished checking my surroundings, my sister is walking towards the car and then opening the passenger side door and sitting next to me. We had the usual really long wait for mom where I try to avoid talking with her because her breath reeks and I have to smell it when she speaks. She tried to start a conversation a few times while we were waiting, but I just ignored her and turned the other way so I would not have to smell her breath. I really cannot remember what she was saying during this time. There was a change to last nights dream when mom was walking to the car. In every other dream, my mom has not surfaced until she is closing up the house and getting in the car. She has always been out of site in the house the entire time my sister and I are in the car waiting for her. In the dream last night, I looked over my should and saw her walking down the steps towards the car. Before she got to her door, I heard her answer to someone and then turn around and walk to our neighbors yard. My sister and I had to wait a while longer while she talked to her neighbor. I remember my sister and I talking about how rude it was that she was leaving us in the car and being willing to tolerate her breath while we talked about it. When my mother got in the car, there was the usual adjusting of the mirrors and then trying to get the car started. I woke up from this dream not long after she had started pumping the accelerator to try to sped up getting the car started.
