Dream interpretation is the attempt to find meaning in a dream. Many different approaches to and methods for dream interpretation exist, historically and currently. One of the most popular approaches to dream interpretation involves looking for associations between the dream and one’s personal waking life, and trying to figure out what the dream means in relation to that. Dream interpretation at its most famous comes from Freud’s Die Traumdeutung (“The Interpretation of Dreams”) in which free association is used to glean meaning from the dream. In this method of dream interpretation, authority over dream meaning is given to the interpreter or analyst. However, this has fallen out of favour more recently. In the ethical guidelines of the International Association for the Study of Dreams, it is stated that authority over the dream should reside with the dreamer, and most dreamwork (which is different from dream interpretation) will usually follow this.
