I had another lucid dream. Like the first one, it was totally real and detailed to me, and I was aware, much of the time, that I was dreaming.
But it lasted much longer. And it was so pleasant and big and beautiful. Everything in it (like architecture) was beautiful, and richly colorful, and interesting, and the people were friendly, I met old friends and made new ones.
It was just like a taste of how much better The Dream can become without the Fear and Guilt. (While surely being not a patch on Reality and Heaven.)
Just one detail, the colors, were amazing enough. I don't often dream enough colors to notice it, but this was just like... a genius painter's version of the world.
Also for a while there I could decide myself where to go in the cityscape (near the sea). I knew I was exploring a dreamed reality, and I was aware that it was shown to me for a reason.
