No one knows. The previous timeline collapsed. Everyone was cast into the abyss in a state of permanent suffering. They didn’t know where they were or what had happened. Listening outside the barrier one could hear only weeping and moaning, in the millions. The operatives, one by one, located the souls of every missing individual and transported them to an alternate Earth dimension. Now this timeline is used as a transitory connection into the civilization we should be in if nothing was disturbed and Humanity was allowed to progress.
This is literally what is described in the ancient texts.
In the actual universe, time flows differently. We’re in a containment field as a result of the time war. In the true universe, a day could consist of a child going to play with a toy airplane.
They don’t need a video game or a motorized version. They’re in a place where the air is visible. it glows, it is light yet electric, just like a dream. As they begin to play with the toy, within a moment they are pulled into a dream which is experienced like a vivid memory, they experience flying their plane. They land in the ocean somewhere next to an island and have an adventure. Then they return to land and meet with some people.
After about a full day of exploring, they return back to where they started and come back to the room they were first in, sitting on the floor holding a toy airplane. The whole event seemed to take many hours yet only a few seconds had passed in the original room. Then, they get up and go to a new location which may instantly transform into a school where other children are learning how to control their mind. Each class is a few days to weeks where the students all live and learn together. Then the ‘sonic reverberation’ is heard and they all move to the next class. An entire ‘day’ of school, lasts an entire ‘lifetime’ subjectively. They know all they need to about the subjects chosen. Then, they head to lunch.
Get it? We’re in a temporal well, everything is gravitationally locked in with a very low minimum of variation. The natural order is much more varied and therefore entire lifetimes of experience can fit into mere hours or days of what we seemingly experience here.
That’s where the original souls come from. There is a controversy whether souls can awake or there are specific number.
