Crazzzy Dream!!

So I had this dream last night and it was like this:
It was 10 o'clock, and my and my cousin/friend/sister (I say it like that because she kept changing). We were in my cousins new White Dodge Ram 1500. Well we were going to Sonic Drive-in. They seemed to be closed, but when we can back by, they were open, so we pulled up. When we got to order, a man came out to take our order (not normal at sonic) and then he tried to saw our license plate off, so my cousin/friend/sister backed over him and got the license plate from him. We both ordered a #2 (double cheeseburger). Well we waited and waited until an Iraqi soldier came out with an M4, I confronted him and stole his weapon, which had the wrong ammo. I loaded it with the correct ammo and. Used to butt of the stock to hit his throat an knock him out. He was yellin at me prior to that and I yelled back like I not afraid of him. Then we pulled up to where they cooked the food, and it was like a Kangaroo Gas Station. And they said they brought our food out and we payed for it and ate it, but we didn't, so they gave us 2 chili cheese dogs and we ate and then I woke up. Can someone help me understand why it has mixed up people and places? And anything else about the dream, sorry this post is so long.. Thanks.
