As a building that provides a sense of direction to boats moving across the water at night, the lighthouse suggests how you are finding direction within you. This is a symbol of your rising awareness as you search for a safe harbor during times of difficulty. You may have the sense of danger or that something beneath the water (unconscious) might harm you. The other symbolism in the dream can provide additional insight into what this danger may be. Since all aspects represent you, the lighthouse is how you are bringing light to your sense of direction.
