It was from a nap late this afternoon. I laid there after the
   dream, processing it. I learned lucid dreaming when I was a
   teenager, so I know if I just lay there and go through what just
   happened, I can hold onto enough significant details to
   reconstruct it later. The numbers were significant as were the
   main parts of the story. Once I was satisfied, I got out of bed
   (probably 5 minutes of laying there thinking about it - not sure
   how long) and I got on with my day. Then when I had a few free
   moments, I wrote it all out.   there were earlier parts of the
   dream as well ,but they're kind in a vacuum - in a
   nothing-space. I didn't take the time to remember those, because
   I found the ending far more interesting, especially the lion
   faced man.
