The human mind is a huge sponge, each second of every day processing information, sights and sounds, directing you through tasks involved in everyday living. In all the excitement, though every activity, bits and pieces become trapped in your psyche. Some of this information is forgotten, or put aside, other times the residue of all the activity affects your nocturnal or unconscious thought.
The human will is an amazing thing. It can guide you to success, steer you through adversity, or just help you cope with what life throws at you. Willpower works through the daylight hours, but can also mold dreams and visions. Like any activity (music, yoga, art, science, theology) dreaming takes learning and practice. With some effort, and most of it done while you sleep, you are able to empower yourself by channeling your beliefs.
