That book by Jung sounds very interesting. I may look into reading that.
I looked the key elements mentioned up and here's what I got. No clue if it helps but was a fascinating dream to read about nonetheless. ^.^
Parrot
To see a parrot in your dream represents some message or gossip that is being conveyed to you. You need to think twice about repeating or sharing certain information. Alternatively, the parrot can denote a person in your waking life who is eccentric or obnoxious. It may also mean that you or someone is being repetitive or even mocking you.
Bookshelf
To see a bookshelf in your dream represents the various levels of your mind where ideas, concepts, and memories are kept. It also suggests your need to acquire some information or knowledge in a situation before making your decision.
Dust
To see dust in your dream suggests that certain aspects of yourself have been ignored or neglected.
Elephant
To see an elephant in your dream indicates that you need to be more patient or more understanding of others. Or perhaps there is a memory that you are holding on to for too long. You need to let go of the past. The elephant is also a symbol of power, strength, faithfulness and intellect. Alternatively, the elephant's introverted personality may be a reflection of your own personality. In particular, if you see a white elephant, then it symbolizes royalty.
Machinery
To see machinery in your dream suggests that you are too mechanical - going about your way without much thought and making decisions without thinking it through. You need to get out of your boring pattern. Alternatively, the machinery symbolizes your mind or your body. Examine how the machinery is running and its condition and function. If the machinery is in need of repair, then it suggests that you may need to repair aspects of your self-image or a relationship. If the machine is rusty, then it signifies an outdated way of doing something.

To see armor in your dream indicates insecurity. You are worried about your well being
Broken legs
To dream that your leg is broken, wounded or crippled signifies a lack of balance, autonomy, or independence in your life. You may be unable or unwilling to stand up for yourself. Perhaps you are lacking courage and refuse to make a stand. If you dream that someone has one leg, then it refers to some sort of failing relationship.
Metal
To see metal in your dream signifies strength and character. It may also symbolize the inhumane side of society. Consider the exact type and shape of metal and what you are doing with it.
Shield
To see a shield in your dream symbolizes emotional and spiritual protection, as well as physical protection. You may be feeling vulnerable and are in need of comfort.
Cage
To dream that you are in a cage indicates that you are experiencing inhibitions and powerlessness in some areas of your life. You are feeling restricted, confined and restrained in a current relationship or business deal. Somebody may be keeping a short leash on you, where you are lacking the freedom to act independently.
To dream that you are putting a wild animal into a cage signifies that you will succeed in overcoming your rivals and fears. It is also symbolic of your ability to control you animalistic rages and anger.
To see a bird in a cage suggests that you are feeling limited in your expression and a sudden lost of freedom. You may be experiencing frustrations and an inhibited spirituality. The dream may also imply that you are feeling like a "jail bird"
