Holy shit, I had one of the most insane nights of dreaming I've ever had, and one of the most insane particular long, drawn out dream. Even when I'd wake up and would fall back asleep, I'd be thrown straight back in.
This one particular dream was basically a horror film. Kinda cube esque. Essentially a group of people and I had to navigate through this huge warehouse (both outside and inside) and avoid these manufactured/genetically modified creatures that were trying to kill us. Plenty of awesome deaths involved, and moment of sheer terror as these creatures would come try and kill us. We had some weapons with us, but most of the time we had to find make shift things around the warehouse to try and defend ourselves. Eventually we made it through the warehouse, but it ended up that it was just the first warehouse in a succession of 3, with another warehouse being built. We made it through to the end of the 3rd warehouse and saw that they were building another one. At the same time as building another one, they were continuing to upgrade the creatures that they place inside, making them more agile and ready to kill. Some how it ended up that next scene was us in a classroom watching a movie, and then being let out of this warehouse that the classroom was in. This warehouse was a normal functioning place of work (or atleast that is how it was portrayed).
Shit was fucking nuts
