And like most videos, it is open to various valid interpretations.
But here is how I see what is happening.
An astronaut is on a mission, somewhere far away in deep space.
We do not know the exact details or purpose of the mission.
But we know that something went wrong, and there is a major malfunction on the spaceship.
Our astronaut now feels drawn to, has visions of, or actually exists in - different places, planets, galactic civilzation. Even their identity and bodily appearance / existence no longer seems to be fixed, or certain.
And a fracture in time apparently has taken place as well, as we see the astronaut trying to fight the malfunction event again and again, as if trapped in a temporal loop.
How will it end? Will our astronaut ever return to earth? Or be stuck in this "heisenberg loop" forever? Or cross-over and live on as an alien in one of the galactic cities they are seeing in their visions?
We don't know. We can't know.
