Sleep: Why do we dream? What are the underlying brain mechanisms? What is its relation to anesthesia?

Out of all theories before his, and all of those today, this is the one that stands out the most. He believed that a dream represented an ongoing wish along with the previous days activities. They may even portray wishes that have been inside us since early childhood. In fact, he believed, every dream is partially motivated by a childhood wish. Another interesting idea was that nothing is made up during a dream and that they are biologically determined, derived completely from instinctual needs and personal experiences.

Probably one of the most interesting ideas among these theories is his theory of dream occurrence. Dreams occur in a state of "ego collapse" when the demands of the Id (imperative bodily needs) and Superego (conscience ego ideals) converge upon the Ego (personal desires and mediator between the Id and Superego). In easier terms, a dream will occur when the unconscious wish is bound to the preconscious instead of just being discharged.

Many of Freud's theories still stand true today, but most of all in the area of defense mechanisms our body uses while we dream. If our minds have been dealing with too much denial, regression, or repression, it causes an internal conflict, a dream in this case, to take place. This prevents us from building up intolerable states of psychological tension in waking life. This is why, if you become too emotional, it actually works to "sleep it off."
