The Erratic dreams of StaySharp

I had a pretty undetailed lucid, I know it involved some odd kinds of fighting, and me walking through a strange building. As I was watching at some scene I can't identify I slowly became lucid but the scene destabilized, my awareness level was raised the entire time but I just couldn't get back into a dream properly. But I didn't wake up either, effectively resulting in me drifting around between awake and sleeping, aware and unaware.
After quite a while a new dream started but I wasn't aware any more.

I've been in a van with this strange dude and a few rescued people and the planet was in a bad state of disarray. We were driving around searching for other people to pick up. At some point we were picking up people in a zone which became instable while we were in it, so as soon as we could we hauled our asses outta there. The driver at first said he wouldn't do the same mistake again but then decided to drive like a jack ass, starting with crushing straight into a house, partially up the sloping road, partially abusing the staircase of the house with now slightly less walls.
Suddenly I was kind of outside the car talking with the driver accusing him of being somewhat stupid because the car was flat like sheet of paper after his maneuvers.

I was in a ridiculously huge sized complex (easily city-size) on some railroads together with my girlfriend. We jumped onto one of the slow going trains and I even had some sort of seat with me, and we stayed a while driving around the complex. The biggest part we got to see was looking like some concrete desert, with nothing interesting around. After some while we came across the more complex parts and I saw crossing railroads, people and strange rooms. At some point we got down because we didn’t wanted to be seen, but somehow my girlfriend was gone for the moment. I went to one of the rooms, which was sort of like a big open bathroom, with a glass door and walls and individually closed cabins. For any very odd reasons I had the keys for the doors and was doing some senseless stuff around there, locking and unlocking the door a few times in the process. Some of the dudes (a lot bigger than me) seemed to be pissed about the possibility of being locked in there. After some short but actually harmless fight I decided to cancel this shit and killed him with fire, he was pretty much exploding. There was some woman behind me, saying something and the scene was changing a lot, looking back the complex was gone and instead I locked straight into a city in bright daylight. I think some water came rushing in from the left, were the street was going down into the main city I think. The dream didn’t stop there but my recall became pretty hazy.

Judging by the city my recall resumed later:
I was in a bus or tram sitting on a seat besides the window on the left of the vehicle. There was a girl sitting on the handrail in front of me and my girlfriend right of her. She told me to switch to the free seat on my right, so I did and she leaned back onto me. We both chilled there for a while till the dream faded.
