The subconscious mind sometimes provides solutions during dreams. It si a known fact even among researchers, but it never happened to me, that I remember.
While I do not say that I am an exceptional case when it comes to the subconscious mind, I do have many experiences with the subconscious mind both during consciousness and during sleep. Mostly they are associated with music, and they help my attempts to create music. I have presented them here under two places...Art and Creative Expression /the Creative Tree and Helpful Announcements.
I have a strong conviction that contact with the astral realm through meditation and the guidance of spiritual masters is the best way to recognize such solutions.
