When one observes a fact without knowledge then one can learn

"When one observes a fact without knowledge then one can learn - 28 May 1967 Why do we dream at all? Isn't dreaming at night a waste of energy, when the brain needs to be completely at rest? When do you actually learn? When I learn through Freud about myself I am not observing myself, I am observing the image which Freud has created about me. Can you do nothing, psychologically? If two people are quarrelling and one stops, what takes place? The more we talk together, the more we communicate together, the clearer it becomes."
