Consequently, what does it mean when the sun rises in the west and sets in the east?
For the moment, let us just think about one motion - - Earth's spin (or rotation) on its axis. Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
Beside above, what does it mean when the sun rises from the West? The sun doesn't rise, it appears that way due to the Earth's rotation. If the Earth's rotation would suddenly stop and reverse, which is what is required for the sun to “rise” from the west, we wouldn't be there to see it as we would all be dead, the Earth in a million peaces from the shock of all shocks.
Herein, when the sun rises in the west and sets in the east then you shall return to me?
“When the sun rises in the west and sets in the east," she said sadly. "When the seas go dry and mountains blow in the wind like leaves. When my womb quickens again, and I bear a living child. Then you will return, my sun-and-stars, and not before." -Daenerys Targaryen”
Will the sun rise from west?
No. But in a very, very long time, it won't rise at all. The Earth's rotation is slowing down. Eventually it will stop with one side facing the sun all the time, just like one side of the moon always faces the Earth.
