Outer body sensation was a bizarre feeling!
Although it was not the first time Soran attempted to project his soul away from the body, it was the first attempt in reality. The strongest feeling was the weightlessness of the soul. It made him feel light and floating without the restriction of gravity. However, it was not that his whole soul had left. In the moment of contact with the light column, Soran's soul had been shaped into a projection by magic, and then directly sent to the gate of the star realm.
Astral projection was only a part of a soul.
It was not the weight of a whole soul, so if it died, it doesn't necessarily kill the body in reality.
However, it definitely would cause damage to the soul!
