'There are no (real) chariots in that state, no horses, no roads, but he himself sends forth (creates) chariots, horses, and roads. There are no blessings there, no happiness, no joys, but he himself sends forth (creates) blessings, happiness, and joys. There are no tanks there, no lakes, no rivers, but he himself sends forth (creates) tanks, lakes, and rivers. He indeed is the maker.

In plain words: In dreams there are no real chariots, horses, roads, lakes or rivers, and no real joys. The dreamer makes all of them up. The Self is the maker of the dream world.
