Discrimination of Dreaming And Nondreaming Sleep

THE DREAMER'S unquestioning belief in the reality of his fantasy creation while he is sleeping makes one skeptical about his description, when awake, of the original dream experience. Even the language he uses to define and describe his dream is restricted to words learned in response to objects and events of the waking world and is therefore inadequate for the description of characteristics which are unique to dreaming.
