Where can I find the scientific interpretation of what I see in dreams and how it's linked to my subconscious?

There is no scientific interpretation. Different things mean different things to different people. That's just the way it is. It's best to go into some careful reflection and meditation and ask yourself what your dreams are telling you. The ones you remember are mostly psychology-related, so you might want to ask a psychologist. Your dreams are your mind's way of sorting out life's issues and anxieties.
