Forced to disconnect from reality because the mind can no longer handle the situation. Entering an alternative within that broken mind, one that is so confused and scattered...is one's only escape from the pain and torment. Some of us have lived through that. It's like a body that goes into shock, and so does the mind when you have a nervous breakdown. The mind looks for ways to sever from the body to preserve life and ease the pain so one can survive. You feel you are drowning or treading water, but sometimes you see a light because there is internal intervention, via angels or other guardian beings.
