Is it not a strange thing that after a night's dreaming sleep when we may become some other person, some other character during our dreams, we yet wake up with the old identity that we had before the dream? And is it not equally strange that after a night's sweet, deep, dreamless slumber when we actually forget utterly that same previous identity, we are able to pick it up once more on awakening? What is the explanation of these strange facts? It is that we have never left our true selfhood, whether in dreams or deep slumber, never been other than we really were in essence, and that the only change that has taken place has been a change of the state of our consciousness, not of the consciousness itself.
