dancing fog

While visiting my friend who lives in the mountains, we fancied taking moonlight walks. One evening I will never forget. We were delayed with our midnight stroll, due to having to attend a meeting. While on our usual path, we noticed lights beginning to shine and brighten from an area nearby. We were able to keep on the walking path while drawing closer to the light. Crouched behind trees we encountered something very strange up around a huge and unusual house. A fog seemed to float right in and gather up around the house then spiral upward in carious places. It was as if the fog was dancing. Tiny orbs filtered about while the fog gre and lit up the sky. My friend seemed afraid and ran home after not being able to speak. I was amazed and stayed for the whole show.
