Cities in the Astral

LD11: In this one I had a very long running vivid non-lucid/ lucid mix. The dream went on for about an hour. In my real life I was contacted in a friendly manner, by an old friend who has been giving me nothing but contempt for 7 years. My brain wanted to fret over the subject in my dreams, even if I wanted a nice pleasent LD. In the dream I would be with him, his new wife, and his loyal friends. I would worry he really intended on poisoning me or what ever. Then I would do a RC, gain reasonable lucidity and fly away from them. I would screw around for about 3 minutes, then there they were again, and I would fall right back into a non-lucid full of all the mental anxiety. That cycle repeated 5 times! So, in an hour long dream, I am lucky if I got 15 minutes total lucidity. My brain wanted to work out its issues in a non-lucid, and fully intended on battling me for the right to do so.
I think it would probably be un-natural and bad for someone to "always be lucid" because non-lucid dreams seem to serve an important function. High points from the short lucid bit. I flew along the top of the Boise River and drug my feet in the water, kind of like water skying. I also had a part where I spider climbed all over some huge buildings. High points in the non lucids. A very vivid explosion and burning building scene, and looking at his new marble floor that was ultra HD. Lucid duration ?~15 minutes (5x3minutes)?
