The process of lucid dreaming is the will to know "I am a fragment of the body. I am the body of a fragment"

Without waking up. To hold on to your "individualism" within the dream. If
you don't concentrate, the apparently paradoxical statement of "I am and I
am not", that you are both the dream itself, an individual in the dream
universe who in a sense is not "real" (this is the mental breakpoint) and
also the dreamer, would will yourself out of existence (ie wake you up out
of the dream)

It take a few tries. I failed at first. Now i lucid dream a lot when i go to bed
