Some people have mostly bad dreams. If I become aware that I am dreaming I stop everything in the dream and "go back to sleep" in the dream. It results in better rest. Everything I've learned in a dream would only be helpful in a world where we wear watermelons for shoes and the trunk of our cars open into hidden ballrooms. It is a really dumb place to spend too much time
My take on dreams is that they're not literal. The mind is structured on a network of symbols and relationships between them, so the language of dreams are metaphors, double entendres, similar-sounds, etc. Why it is important is because it tells a story about what's going on in your emotional state that you're otherwise unaware of or repressing in conscious experience.

The problem with using guides and interpreters is that you don't know whether they explain your unconscious associations, or just substitute their own.
If you interpret your own dreams, you can be sure that all associations were generated by your own brain. Maybe during the dream, maybe during the interpretation. Who cares; either way, it's about your brain.
My simple interpretation method is to write an outline of the dream, and to some words add an arrow and write what it reminds me of. Usually at least three things in the dream remind me of the same topic -- that is the core message of the dream.
