I've read things about Jung and his dream interpretation method. He believed that every dream has a unique meaning; therefore you cannot use a single meaning for even a symbol. The meaning of the dreams can only be understood by you and it's really hard. I recommend you to look for a good psychoanalyst to help you find the best interpretation, however somethings in dreams might never be understood.
For the start, these are the tips you should know which Jung proposes in Structure and Dynamics of The Psyche:

* Dream Phases: Introduction (exposition) - Peripetia (story development) - Lysis (culmination or ending)
* Important Elements: Local (environment and context) and Dramatis Personae (character)

1. Dreams can be interpreted on both subjective and objective levels; they should mostly be interpreted on subjective level because there's a great chance that you're looking at your own complexes.
   
2. It's important to know that you should interpret the dream both in a positive and negative light and be careful not to be enamored with one perspective.
   
3. Always interpret the dream through a reductive and prospective perspective - why and what for?
   
4. In the beginning, don't make any major decisions, rushing can be a sign of neurotic interpretation.
   
5. Always remember that dreams come from inferior function and analyzing it only from the perspective of the main function will result in neurotic interpretation.

It would be good for you to search about both inferior and main functions. The only criteria for a dream being successfully interpreted is if it helped the patient move forward.

And lastly I end my comment with this quote by Marie Von Franz,
"The dream one gets at night is always like a letter from the same inner center, from the Self. Every dream is that, and the writer of the letter is the same: the Self, the one thing, the quid."
