In my dream I was walking down a road in a city, not lucid yet. Then I spot off in the distance a gray fog, which I sense is the edge of my dream. This intrigues me, and I rush over to it. I'm becoming lucid now, sensing that this rolling gray dream "fog" is the edge of my dream somehow and it is the stuff my brain hasn't yet transformed into dream scenery/imagery yet. It is like I got lucidly ahead of my dreaming brain and it didn't know what to create yet.

At least I had lucid control to create stuff out of this fog. I imagined a few machines into existance, and they appeared out of the fog near me. As I started messing around with the machinery the fog started to clear a bit, then roll back revealing the landscape I was on. I also did other lucid things, you can see my DJ entry here.

The fog seemed vagely familiar to me as if I had encountered it before in dreams. Has anyone else had encounters with a dream "fog" as I have described it in their own dreams?
