Dreams are imperfections of sleep; even so is consciousness the imperfection of waking. Dreams are impurities in the circulation of the blood; even so it's consciousness a disorder of life. Dreams are without proportion, without good sense, without truth; so also is consciousness. Awake from dream, the truth is known: awake from waking. The truth is: The Unknown
