I just had a thought I wanted to jot down...
Per my previous theorizing I have speculated that the cortical maps in the cerebral hemispheres are important structural elements in understanding how dreams are composed. I just had a thought that the ideas of both circumambulation and cortical regions are relevant to when a dream changes scene.
What if a dream scene change is correlated with a change in the locus of the cortical region that is underlying the dream? No one cortical region can generate a dream but there may be a need for the brain, in producing the dream, to effect a scene change if there is such thing as a "primary locus" of brain activity changing over the course of the dream.
Just a thought. Although it sounds like something that might be amenible to scientific verification, I think the issues with dream recall and coordination of time lines with waking world time measurements of brain activity could be highly problematic.
