Dream - Low purple clouds and disaster

Long ago, perhaps in the mid 1980s, I had a dream of very low purple clouds, low enough at times to touch. There were flashes and tornados in the clouds, I think even a disastrously large tornado or two. I think maybe a UFO or two as well. Most of the time I watched the clouds from the ground, but I think I also flew above them at times. The clouds were very threatening and seemed like a psychic phenomenon of some kind, and could somehow bring about or carry with them something that could bring about the end of the world.
