This is actually a pretty good dream. It does have good meaning, and I do believe you will see some positive effects soon.
First off, the boy. For everyone, there's levels of masculine and feminine selves. The boy would represent your one of your masculine selves which is just above your normal waking self. Being a child shows that it is still somewhere in your subconscious. That you came from jupiter is a very good sign and clearly fits the sage part of your name. I admit I have been pondering about your name, and am fascinated that this dream you share, well, lays it bare.
Police are enforcers of law or rules. Law can help bring order, though laws can sometimes bring oppression. Trees: some of the thoughts that humans project become trees in other planes of existence. Pulling trees out of the ground and clearing away police cars, could very well mean that you will focus your thoughts and question age old beliefs, thus liberating your mind to better understand guiding messages. You will possibly also let go of old identities.
Consider, core beliefs usually act as filters that filter the messages being channeled to us. Initially, this is a survival thing, though much of the shaping of these beliefs is also from our environment, upbringing and genetics. Having core beliefs is essential, just that once in a while core beliefs need to be shaken up and reshapened. The reshapening of core beliefs, to be based on experiential knowledge, will allow much clearer messages from guides and higher selves. Since you have already had this dream, I believe the process is already under way.
Your dream also seems to say that initially it will be hard for you to understand these messages and you will unconsciously try to avoid them. There's nothing wrong in that, so just relax. Think of it as your system trying to adapt slowly to the otherwise shocking change. There will be some resistance, that is natural. Just have patience and faith that eventually the new 'language' will be comprehensible to you. Think of it like opening your eyes for the first time after surgery. It will be blurry, and slightly painful at first, but after some time you will regain clear vision.
So, I hope the next step of the journey, will be exciting for you, for it sure sounds exciting to me.
Keep the love flowing.
