What is with these nightmares?

Dream.

I was in a big group of people rounded up... it essentially was like the Nazis/Jews, except I don't know what reason they were giving. It's kind of blurry until we were all in this big auditorium (with seats for the audience and a stage, etc). They were putting names and the person's status up on a projector, and I saw my name with "D/co" next to it. Apparently that means I was going to be suffocated in a coffin. We left the auditorium in a bus after all the people who were going to be executed in that place were, and we drove to the "coffin suffocating" place. I was looking for a way to escape, naturally, and when the driver pulled too far over to the right next to a steep embankment that led down to a swamp, I yelled "Everyone lean to the right! To the right!" and everyone jumped over to the right-hand side of the bus. The driver lost control, and we all fell inside the bus down about 40ft to the swamp. Crawling out a window, I could see everyone running into the swamp/woods, as did I. At the other end of it, I found this city (seemed Mexican??) and waited to meet up with other people. I met up with one person, and we wandered around because we didn't know where we were. Some officers who were looking for the escapees found us but we killed them and took their suitcase full of money with plans to get passports and run away somewhere. I called my dad (because apparently my cell phone was still in my pocket) and then my alarm woke me up.
