Nobody can tell you what your dreams mean. Only you can make that determination. It is your own psyche, and your own set of rules, even though they are subconscious.
Firstly, if you want to start analyzing your dreams, I suggest starting a dream journal. As soon as you're awake, write your dreams. You will remember them more clearly, and be able to revisit them to look for themes and other progressions.
As far as analysis, you need to consider what these things mean to you.
By the way you are presenting the information, you seem to already have an idea of what you think these recurring themes are, and you are attempting to lead the answers by your question. If that is the case, then you have the answers you seek already.
