We always dream in pictures. You may hear words in your dream but the dream itself will be in pictures. Likewise, everybody thinks in pictures every now and then. Throughout our entire life we create thought pictures of our self and our life that become memories and wanting to fulfill them. Some of our pictures that we dream are formed through actual experience, others are only imagined - but all become real in our experience of them. Together they form the blueprint for our subconscious which will arise to the conscious level of ours and then makes us feel the experience. It will give us a clear situation and drive us to work on them on the real world.
