"Sargon lay down not to sleep but he lay down to dream"

I have been saying for decades that dreaming is not fundamentally about what happens during sleep; it is about waking up to a deeper reality. I found confirmation for this understanding in a Sumerian text that is a mere four millennia old. It is the story of "Sargon and Ur-Zababa". The famous Sargon of Akkad began his career as a cupbearer to Ur-Zababa, the Sumerian king of Kish around 2350 bce.. Ill and anxious, the ruler of Kish asked Sargon to dream on his behalf. We then read "Sargon lay down not to sleep but he lay down to dream" Sargon's dream brought no comfort to the king.He saw the goddess Inanna as a beautiful young woman "high as the heavens and vast as the earth" who drowned Ur-Zababa in a river of blood. Ur-Zababa tried to have the dreamer killed but he was the one who died and Sargon took his throne. The people believed, because of his dream, that Sargon was under the aegis of the great goddess.
