I have very long story arch dreams, an ex-girlfriend called them epic dreams. They're strange, some times I have recurring dreams with long story arcs in which I am in them as myself, sometimes I am in them as another person, sometimes they are narrated, sometimes they span generations, sometimes I'm not in them at all, sometimes they are episodes of a tv show that never had those episodes.

Examples - one dream was set in a post apocalyptic wasteland, sort of like A Canticle for Leibowitz, with narration, there was a kingdom being misruled by a duke and the only one who would be able to stop him was the exiled bishop, his brother, I turned out to be the bishop - an old man returning after many years of exile to the kingdom etc. etc. there were sword fights, radiation monsters, extra sensory perception..

Another dream was a very long special episode of Laverne and Shirley were the girls came out and had their first kiss, I think it was a Christmas episode also.

Actually funny enough I had three dream flashbacks just a couple days ago, first I remembered a comic book store and then I remembered no that store was from a dream, then I remembered a couple other locations from dreams that I had not had for lots of years and had forgotten about.
