The fluidity of narrative.

Weird dreams.  At the beginning of the night, I was Robin and fighting crime with the Teen Titans.  Then, as the dream progressed, I became Indir from Madcap Archaeology, the Titans became the rest of that team, and we attempted to outmaneuver masterminds of organized crime, lead by Malcolm McDowell, who were trying to trap Vessa into an organized marriage.  I think.  Identities kept changing.  And most of the dream took place in or around massive sepulchers in a cemetery that seemed to stretch on for miles in every direction.  In any case, there was also rather a lot of sex in that portion of the dream, which I am not planning to relate in details but which was more than slightly mind-blowing.

In the third stage of the dream, I was the Doctor from Doctor Who... alternating between Tom Baker and David Tennant...  and the Master (John Simm) and I were working together, attempting to navigate a shapeshifting house in order to find where Malcolm McDowell was holding Romana prisoner.

The thing making this dream unusual was, I think, that even within the dream I could remember the shifts in narrative.  There was only a limited sense of continuity to my identity -- sometimes I remembered the previous arcs of dream as though they happened to me-as-a-different-character, and sometimes I was only dimly aware that in this story, there were many people who were very unhappy with Mr, McDowell and his extremely well-tailored white tuxedo.
