Over the years I've had many recurring dreams set in the same or similar places such as my high school (argh), places in SF and myriad surreal/fantasy settings. Occasionally a dream in one location will transition to another one, usually through my dream self finding some sort of passageway that leads to a completely different place. For example, the dream version of my high school is a byzantine nightmare of dim passageways and staircases. Every now and then I'll come across a ramp which starts underneath the auditorium and spirals downwards. The impression I have here is interesting by itself, I feel like I'm winding my way inside the spiral of a snail shell, or the inner ear- ANYWAY, the spiral ends up dropping me off in San Francisco, a twisty street version sort of reminicent of Lombard. I've found a bunch of places like this that transition one dream into a different one, and they always work the same way and go to the same places. This makes me think that maybe my whole dream universe has its own topography. Anyone else have a similar experience? Has anyone made a map?
