Dreams.

I had a dream today that I ended up in some strange place from which I couldn't leave. There were no visible obstacles to this, but the fact that it was forbidden didn't change. I wasn't alone there; there were other people, most of whom were clearly not entirely mentally sound, while others seemed fine, or were simply pretending to be. It's unclear why this place was created; nothing special happened there, and life went on in a rather dull way, like a pale imitation of real life. In short, I spent ten years there. That's what the dream was like.
