Another hypothesis is that dreaming plays a role in memory processing, especially with emotional memories. During REM-sleep, the amygdalas, which play a role in the formation and consolidation of memories of emotional experiences, are quite active . Dreams are mechanisms that inform and guide our feelings and emotions. In short, this theory maintains that dreams are a way for us to express our desires and fears that, for whatever reason, need to be expressed but are not expressed when awake. If this is true, it would seem to follow that only one very intimate with the dreamer should attempt to interpret a particular dream.
Dreams are very personal and speak to the specific emotional life of the dreamer.
This theory seems to be based upon the fact that most dreams are about things that have occurred within the past day or two and reflect the dreamer's present life and concerns, including unresolved feelings. We may have anxieties or desires that only our dreams can reveal. We may not have been aware of our desires or fears until they were awakened by the dream. Sometimes our symbolic dreams are so clear that we do not need outside assistance to help us interpret their meaning. Yet, many dreams are so strange, irrational or bizarre, that we are at a loss to find meaning in them.
