You visited a location in dream.
Really do you want to do anything to take away the majesty of that, to render the wonderous ephemeral expanse inert by cold analysis?
Maybe its just your nuerons firing wildly as seratonin bonds decompose in the daily process of your nervous system rebooting itself, maybe your uncoscious mind concocted some sort of narrative vision for you to enact so you could learn some sort of lesson, maybe in sleep perchance the dream was a door to another world. a better world, the real world where none of us is handicapped by petty physical constraints...
Perhaps you sauntered past the very gateway to Heaven and didn't know it.
