Djed-pillars are Egyptian artifacts.
When I posted my dream about Flying Sleds on a dream Facebook site, asking, “If someone recognizes a certain symbol / form I saw in a dream from somewhere, please share.” Someone posted information about Djed-pillars, which I had never seen before. It is so much fun when a dream shows you a mystery and then it is solved in our day-to-day world.
