Traumas create parallel minds.
They are not beneficial to you, and they get you more stuck into the matrix.

Old shamanic traditions used severe traumas for initiations. (very different per tradition).
It enabled them to see more than the average person.
But it also made them a bit psychotic to very psychotic.
African traditions are usually very psychotic.
Many traditions use all kinds of drugs.

So instead of escaping the illusion or matrix,
they got stuck in a deeper level of the matrix.

My impression is that people with an accidental Near Death Experience
do get some glimpse of what is outside the matrix.
So we will get there naturally, but meditation can also help.
They also tell us that our life has a purpose here,
and the experience makes them live a better life.
