A fragment of a dream that returned upon reading about aurora's on Mars (How the Sun Helped Murder Mars: http://time.com/4099730/mars-atmosphere-maven/).
I am speeding along on board a silver train with large windows. There are others aboard and we are suddenly aware that rainbows are appearing on the horizon. Not just one or a double but many with standard appearance and varying sizes. They seem to emanate from everywhere and excitement mounts on the train as new ones sporadically appear and are pointed out by the passengers who ooh and aaah. At first appreciation is in unison, then, because of the unexpected number, the shouts are more singular alerts as to a new version in the sky. The larger ones are multi-concentric and variegated with complex designs and color patterns, somewhat geometric but still in a circular arch formation. The windows on the train don't seem to accommodate the magnitude of their scope and I must bob and weave my head to take in the full arches between the mullions. Passengers crowd around the southern windows of this west-bound train to witness the unfolding phenomenon and accumulation of rainbows. I am entranced, but begin to question the puzzle and scientific reason for this happening …quietly to myself.
