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." ] (More)
