tecnico82 While Freud's classic work, "The Interpretation of Dreams" (and a condensed version he titled simply, "On Dreams") declared dreams as "symbolic expressions of our unfulfilled wishes, disguised," current research has found little to no evidence to support this claim. The current understanding of the function of dreams is rather simple: dreams originate in the hippocampus as the mind's highly symbolic interpretation of our current life. Obviously, many of these "interpretations" are so complex as to be less than obvious in their meaning, but they reflect the mechanism the brain uses to help us "understand" and learn (and this reflects the brain's "executive function" ability to incorporate new information into the stream of already known information). The more complicated the dream, the more the mind is working to understand. Obviously, as we learn more about the functions of the mind, further theories may emerge, but until then, all the rest of the ideas - communicating through dreams, etc. - can be summed up by Pepe in the word, "hoohah."
