When we fall asleep, a world of dreams appears in which there are people. As long as you keep dreaming, that place will be there and those people will be there. That dream will continue. If you wake up, it will disappear. None of that exists without your dreaming. It's your dreaming which is sustaining that dream universe - just like god plus mia sustains this existence. And then finally, destruction. Pralea prale means dissolution or destruction. What happens to the dream universe when you wake up? This physical universe also is resolved back into into maya, the power of consciousness, at the end of the universe.
