Dreams tell us a lot about ourselves. My Danish-therapist friend, Birthe, would be the first to confirm this truth. She has counseled me often that characters who appear in my dreams "are part of you!" Not only is there a direct psychological link, often there's a spiritual dimension too.
How many times did God give a dream to direct, warn or transform someone? Just a quick look back shows a dramatic sampler: Joseph son of Jacob, Solomon, Daniel and Joseph father of Jesus. In all those cases where God gave a dream, he brought fulfillment (or is still in the process of fulfilling, as n Daniel's dream of the end). If God spoke to them, why not me?
My recent dreams have had a focus on manuscripts and publishing. Vital to interpretation is prayer, plus context. As I pray into a dream and ask the Holy Spirit for his meaning for my life, I observe what's going on currently. In this case, I'm writing a book and hoping to complete it by year's end. Dreams need fulfillment; I'm anticipating!
