A few weeks ago I had a dream about the Justice League of America. Now that's bad enough in itself, but as the dream progressed, my subconscious mind began to correct the dream for continuity errors. For instance, at one point Superman used powers that he had had prior to the mid-1980s revamp of the DC Universe. My subconscious mind actually interjected, "No, that was Superman from Earth-2, which was dropped from continuity during 'Crisis on Infinite Earths.'"
I have never been so ashamed of my dreams.
