The reason of tying into the unconscious is not only life saving. It is an intrecal part of the awareness system, which is not allways under life threat.We've all experienced this at some time, I expect. It's a fundamental life-saving function!
Becoming aware of the rerouting is not standard. If you are aware of it, there is a fault in the system. Usually being tired of maybe a trance.
But, maybe there are other explanations. These are valid for those who experience them. For me the question remains: how do youseoperate them.
