But the characteristic of this side of the dream life becomes complete only when it is remembered that while dreaming we do not—as a rule; the exceptions require a special explanation—imagine that we are thinking, but that we are living through an experience, i.e., we accept the hallucination with full belief. The criticism that this has not been experienced but only thought in a peculiar manner—dreamed—comes to us only on awakening. This character distinguishes the genuine sleeping dream from day dreaming, which is never confused with reality.
