We were all in some kind of real-life version of The Exorcist. It was like a theme park ride, but much more real and much more dangerous. We were trying to find our way out. There were demons everywhere. People kept looking at their hands and seeing little bugs crawling all over them. This drove a lot of people insane. Eventually, we discovered that the world we were in was a shared hallucination created by the bugs. The bugs had swarmed in through our mouths and filled our bodies. They were symbiotic. Once we learned to accept them and live with them, we didn't see them anymore, and the world became less frightening. It was still an hallucination, but they made it a nicer one, once we stopped fighting them.
