Dreaming is alignment work: the brain seems to rehearse tomorrow by compressing the day, folding metaphor into metaphor.
You wake with only the shimmer of the story - and later might realize the shimmer was the attempt at a predictive map.
When you want to improve communication with your subconscious and learn more about yourself, it may be worth exploring speaking to yourself in symbols and metaphors - condensing your message into sequential visual patterns. Perhaps, through dreaming, your mind will respond.
