It happens to me that I am watching a dream, but I am conscious. Like I am in a dream, but I am not sleeping, I cannot move my body, but I know I am not sleeping.
I was analyzing that the moments just before sleeping or after waking up are special moments. If we can master the art of controlling those moments, we can enter a realm that is unique. That will bring us knowledge that is infinitely greater than the current knowledge we have. It sounds like fantasy, but in my experience, it is possible.
