It sounds like a Philip K. Dick story, but we all have custom crafted dreams. It is just how our mind works.
I take that for granted. I mix in what I glean from my dreams with the rest of my complex and abstract understanding of reality. I assume that it has meaning outside of me, or that it originates from outside. Probably because all the content is remixed in my brain.
So when I wake up and am too upset to go back to sleep, I have to keep in mind that the dream was not the world passing judgement. It was me.
