Freud's writing rejected the existence of dream interpreters or terminology explaining meanings of dream symbols. He said the significance of all dreams could be studied through personal experience as self analysis would be the best to study one's own fantasies. Freud was a firm believer of the theory that every action and thought has a cause probably entangled with the unconscious mind. Every dream has a symbolic notation. It is a representation of our hidden pleasures and desires which our ego has guarded in day's light. In the blackness of night these pent up urges get outrageous and find way through dreams, even healthy minded dream. The content or stimuli to these dreams could relate to any present or past event of restriction.
