There are many books written upon the symbolism of dreams, how-to books that attempt to interpret for you what your dream meant.
Their value, however, depends on how much you are a product of the society that prints them. While there are unquestionably archtypes, everyone has somewhere their own mythology, and unless you have read and reread those dictionaries you are liable to find many of your dreams don't fall within their pat categories and conventions. Should you find they are, question how indoctrinated you've become, that your dreams so closely resemble everyone elses...
If you've written your dream down quickly after waking you will often find that it's interpretation becomes clear. The relationships, the problems, the events will explain themselves. Leaving it, however, and brooding upon it leaves it open to the reworkings of memory, and memory will often reshape and rebuild the dream each time you return to it; eventually your memory of the dream bearing no resemblance to the dream you actually had...think of it as a mental game of "Chinese Whispers". And this will make it's interpretation difficult.
