Dreams and the Not Yet Experienced

Have you ever had a dream where you experience something that is totally new, totally unique, something never experienced in your life?

How does your imagination come up with such things if they are truly new and unique?
In the words of a wise man, "I don't know!  But it's cool!"

There was a dream in which I entered a cathedral; which had as its composition, not stone and wood, but gears, pulleys, and crystal.   The vaulted, hexagonal ceilings, arched up, with canvas and twine and steel ropes, braided into the curving walls, with a six point brass pulley at the apex of the ceiling.   Each door was constructed of gears meshing together in a rectangular arrangement, with the teeth blurring the lines between the door and walls.  The floor was of polished discs of metal, spinning together, but when my foot was placed upon them, they stilled, and started up again when I removed them.

Where the altar was supposed to be was a clear crystal box, ten feet on a side.  Several crystal plates were spaced inside, with patterns etched in each plate, and all were moving back and forth.  As the plates moved, patterns would line up and opening appear.  When this happened, water would rush out of the crystal box and cover the floor of the cathedral with a sparkling sheen.

Up at the highest point of the cathedral was a machine like a golden clockwork from a pendulum-driven, grandfather clock.  Each gear was glowing gold, moving around a central hub; changing shape from a diamond outline of 11 gears to a star configuration and back again.   The light coming in from the sky, struck the gears and illuminated the walls and ceiling with ever-changing configurations of light.

What was amazing is that the whole thing was forever moving.  Ropes would stretch as gears would turn.  Water would come in and then drain away.  Geometries of light and shadow were forever changing.

What kind of dream is this to be having?

There was so much going on, such intricacies and perfect timing in the clockworks, that I knew in the dream that this must be real; for my mind could never conceive of and visualize such a perfection of machinery.  Or perhaps, I could?
