Dreams.

I had some kind of action movie dream today. But I barely remember anything.
I was shooting people with an assault rifle through a door. And at the end, we were escaping and got into a car. But me and someone else (I think there were three of us) decided to go back because we needed to retrieve some kind of bag or something that had evidence against me. In principle, it wasn't even necessary; I could have talked my way out of it somehow, but it was better to take it. So my partner and I headed back there, and people with assault rifles came toward us. And they started shooting. I yelled, "Run!", but my partner just lay down on the ground, ha. I actually felt ashamed that I was a coward and a noob, while he knew what to do (in the dream's reality, that was exactly how you had to do it). I looked at him and lay down too. And like, people were shooting over us but didn't hit us, even though the distance was about fifty meters. Then the burst ended, we jumped up and ran back to the car. But a sniper shot him in the knee leg, and then they finished him off completely. Me and the remaining person (I think it was a girl) were wildly upset (we lost a friend) and drove away.
Actually, I think we were robbing something there and completed the mission. In the bag I wanted to retrieve, there was some other looted expensive stuff, but not as expensive as our main haul.
And yes, at first it took place in some house or building, seemed abandoned (again), we were shooting, escaping, pursuing, and deceiving each other there.
