Will once told him that there was once a person who found himself in that area. Of course, like most of Will story, the story is told to him by his teacher.
This person body was disintegrated leaving only the soul.
It wasn't until he realizes that he is the one creating that world that he finally got a True Soul and manage to leave the area.
Will did not exactly know what happens afterward to that person. What matter was that Azief remember that Will once tell him of such a phenomenon
And in that place, the soul is feeling empty and helpless.
The soul only had its thoughts but not physical body
And it is because of that the soul could not sense the passing of time, but the mind is constantly thinking
It is actually better to die than to live like that. At that time, that person did not remember his lives and why he was there
All the soul could do was to slumber.
