The metaphysical purpose of prenatal trauma?

[EvolvingPhoenix]

So I've been wondering... Let us say that a soul chooses to program it's incarnation to experience some sort of trauma in the womb. What metaphysical purpose does all this catalyst serve? Is there some sort of balancing of love and wisdom to experience? Is it meant to teach some important polarizing lesson? Why create trauma that can't be consciously remembered nor socially acknowledged or even known about by the general public? Is this supposed to be a polarizing experience?  I'm trying to understand why a soul would put itself through all this. What is the intended metaphysical payoff?
