Dream: navigating by streets I've never seen

I'm in the back of an old cockpit, pre-GPS, and my charts show a coastline that isn't there anymore. I keep calling out headings and nobody answers. Below me the ground is lit up like a city grid, and somehow I know every street by name even though I've never set foot there. I wake up right before I figure out whether I was lost or exactly where I was supposed to be.
