I had one of those dreams during waking that was both vivid and meaningful. It was in a village, with many people around. Standing inside, but near the lip of a basin. There were trees, complex terrain, but not a lot of big rocks. Everything was lush and green in the late afternoon, early evening. Before dusk, but no direct beams of light seen.
The basin wasn’t actually a basin. It was curved spacetime. Gravity did not “feel” strange, but it did “look” like we would walk down into the basin to go forward. Left and right seemed normal. Perhaps the Earth had become a Mobius Strip in spacetime, not a torus. We were looking across the gap from the inside.
There was no Sun in this universe. It just became brighter and darker over time. Shadows were always towards the center of the strip, but if you looked behind you, you would see the curce of the Earth going upwards.
We were looking up at the moon. The moon was physically smaller, but seemed much larger because of how close it was. It took up maybe 5-10 degrees of arc worth of the sky. The moon travelled perpetually in the center, because really, it stayed stationary. The Earth’s surface rotated continually, almost flowed, across the Mobius, dragging atmosphere with it.
Left to right, there were lots of cirrus clouds, with a thick line of them. You could see the clouds striking and billowing against the line of clouds. No dust was coming off of the moon, and it was very dense — more massive than IRL.
In the distance, instead of blackness, or stars, it was the darkest blue. You could see the lights of night-time, creating an outline of the entire continent of Africa, isolated, without Europe nearby. It was almost directly across it seemed, but it was also up vertically because of the curvature.
We understood, all of this in a way, because we had grown up with it. This was still an amazing sight, just like IRL how people get excited for a solar eclipse, or a blood moon, or a comet, or a meteor shower, or any other less common movements.
