"I am very interested in consciousness. Sadly we have some limitations imposed to prevent us doing anything."
We all begin with only our natural abilities, and then study and practice to expand and gain new ones. The lessons I take are designed to remove the barriers on our consciousness, and when they've worked I've seen energy and auras for a minute or so quite a number of times before it wears off.
As for the information in the dreams the evidence and teachings point towards a universal consciousness, not so much an individual but a storage facility, and when we dream we can hook into it and gain information as it is sent to us. Musical composition, especially as if heard from a performance rather than worked out over time, is beyond most people, and even the professionals have had complete concerts played in a dream they wrote down and performed themselves. Dreams give us the easiest door into these realities, and as ukanonymous said, the thought may well be the key to creation, and God may be you and me, as Neale Donald Walsch says, we are made in the image of God, not vice versa, therefore we are small gods, God is not a large person. Then it works perfectly, believe or not.
