In psychotherapy, much attention is paid to dreams. As the uncensored product of the unconscious, dreams provide excellent material to work through. A single dream could occupy a whole session or more. The associations of the dreamer are the most important in this work, but archetypal symbols can come "pre-loaded". The picture is rather similar to an image in a dream experienced by a friend. The dream revealed her feelings about her husband being "a horse of a different colour". This particular image is from a museum's Indian exhibition and could fall within the Vedic tradition (I am open to correction). In the Rig Veda, one or seven horses draw the chariot of the sun. A votive red horse was found in a Celtic hoard excavated in France and is thought to foretell war or destruction (as in the Apocalypse). And the dreamer's dream? Yes it did presage conflict.
