(Shane is my original character created for a bad-fanfiction-waiting-to-happen based on the universe of the movie The Chronicles of Riddick. Shane is Richard B. Riddick's daughter and looks about 12 years old.)
I started this dream as Riddick, let loose in a large prison environment containing some sort of haphazard structure in the center of a gargantuan "room" that had a dirt floor and extremely sparse plants scattered around, almost like an enclosed biosphere, except square and surrounded by walls and a ceiling. I was closest to the central structure so I climbed to the top, killing everyone on the way, and becoming "king of the hill." More prisoners were drawn to the fracas and were going to attempt to take me out.
Then the powers that be released zombies into the grounds. As Riddick found his own way to escape, I became Shane who was busy running from zombie death. Toombs was right behind her, apparently the bounty hunter had managed to land himself a prison sentence. I ran to the nearest edge of the building (it felt like the east side) and saw a hose in the corner (south-east side). I turned it on and was quite happy to see it actually worked at all. It worked well, and I was able to fend off some zombies with the jet of water as they didn't like it for some reason.
There was a line of windows above me, and I could see that the closest one was open but not normally reachable by one person (great prison security, eh?). Toombs was asking how anything I was doing was helping either of us get out as I wrapped the end of the hose around my waist. I told him to watch me and do what I did after I got up to the window. I turned the water on real hard, and the force of the water in the house lifted me up. I was able to guide the direction in which the hose lifted me and was soon up on the window ledge. Toombs turned the water down enough that I could throw him the hose, and then had some trouble getting the hose concept to work for himself until he realized he was heavier than I was, and needed to turn the water up higher.
Meanwhile I jumped out of the window, a little afraid I might hurt myself on the way down but at this point it was better than being eaten by zombies, or staying in prison at all. I made it okay and started running away from the prison into the semi-darkness before morning. I looked back to see Toombs reach the window's edge; he was too large to fit through the gap I'd just left through, so he just kicked the whole window out and dropped to the ground to follow me.
There was a problem with the landscape now: further east was a sheer cliff going upwards that joined with a mountain range to the northeast, to the south was an impassable ravine, and to the north and west the country was flat red clay and dust with no cover for quite some distance. It would take much too long to run anywhere and surely the prison guards would recapture us out there. But to the northeast was a cave that went into the cliffside, so I headed for that even though I wasn't happy with the lack of choices. I had a feeling this was the way Riddick had gone, but I couldn't see him anywhere and put that thought aside as there were more pressing matters to attend to.
At the entrance to the cave was a skeleton sitting in front of a campfire that was currently in full-flamey-swing. The formerly-living looked as if it had starved to death or something, and in its bony fingers it held a tea candle in a candle holder. The candle was lit (yet its owner was long dead, go figure) and now I became Toombs as Shane took the candle and ventured into the cave ahead of me. It was a poor light source but better than nothing, as I had a feeling we'd need it (I somehow knew there might be light-fearing aliens on this planet like the ones in the movie Pitch Black).
The spaces we crawled through were rather cramped, and in a larger area the ceiling was still so low that Shane had to duck. She stopped for a moment, and I warned her just in time before she moved again; I grabbed her shoulder, there was a flock of those nasty tiny creatures right over her head. She ducked further to avoid them, as somehow they hadn't noticed us (yay alien sleep?) and we entered another room barely larger than the last.
Here there were two dog-like creatures, each about the size of a large housecat. We both knew they were vicious, insane creatures who would eat anything that wasn't one of them. I became Shane again (which put me closer to the dogs), and at this point we couldn't turn back so I pressed forward, slowly, trying to exude the feeling that I belonged here, that I was actually one of the crazy doggies and everything was cool. The problem was, they'd acquired a large chunk of meat that was some poor hapless thing's former body. It was in the way, considering the two dogs were on either side of it. And on the far side was the exit from the cave, I could see daylight beyond.
One of the dogs was snoozing while the other munched half-asleep on the body. All I could really do was move into the corpse, and unfortunately the end that moved was the end the awake-dog was eating. The dog whined in sleepy annoyance and I tried to make generic "I belong here too, hello doggy family" noises. Amazingly, this worked, and I was able to get past the dogs with Toombs following right behind.
It was a massive relief to get out of the caves finally, and we found ourselves in a small, meandering canyon of the red clay stuff prevalent to the area.
Then the dream logic bailed on me and I'm not gonna get into the rest.
