I have been told that the last thoughts one has before going to sleep sets a stage for one’s dreams and the dark night. Having no evidence outside of my experience to support the theory, it is interesting to consider how many answers to lingering questions are answered with the dawn. In my experience, the cause and effect correlation drives a habitual desire to be intentional, even when I sleep.
There are two warnings I would share with anyone thinking of being intentional with one’s mind when you are in control. First, be careful what you ask your mind to think about because it will! Second, have a double think about one’s choice of topics. The mind has a bad habit of giving you honest answers to your questions. When you wake up knowing the answer to a question that you have been comfortably living with in denial, it is hard to ignore what you already know to be true.
