I actually must've drank some nightmare fuel last night before I went to bed.
Basically, it was some sort of horrible version of Groundhog Day where every time I fixed one mistake some horrible thing cropped it's head up.
One that stand out in particular was where I was holed up in some sort of office complex, one of the newer shiny ones that are almost all glass; with my girl, my supplies, and my guns. Stupid place to be in some sort of emergency but it was a dream so cut me some slack. Anywho, round one I was being complacent and two burly and none too friendly guys came in right through the front doors and clubbed me upside the head.
Second time around, I was right back where I started. It took me a while to shake off the shock when I remembered what I needed to do. So, I grabbed my gun (don't even recall which one) and sprinted to the front door. I could see them coming and they could see me. Well, I slammed myself against the door in order to block it while I figured out a way to lock it. In my haste I'd dropped my gun just out of reach and I couldn't get to it while bracing, a la that one scene from Jurassic Park. They eventually just over powered me.
Third round I managed to remedy my previous mistakes but still couldn't figure out the way to lock the door. As I desperately held the door shut it finally locked and I breathed a sigh of relief. Then I looked up to see one of the perps raising some sort of pistol. I woke up right after I saw the rounds penetrate the glass.
Seriously, nightmare fuel. It doesn't help that that wasn't the only such dream but it was the only gun one.
