I once spent 12 days w/o sleeping. I was so peaceful that i just did not sleep. I did everything just the same w/ regard to eating.
I also saw the world differently, that is, from an entirely different perpective.
It was this experience that led me to thinking about the brain & then on to CRI w/ holosync technology.
I know that that experience, by the 12th day, was beginning to concern me.
