House of the Unconscious: solitude, spirituality, hidden patterns and the subconscious. With Mercury here, that area of life carries a curious and analytical signature.
Here, Mercury asks to be noticed through inner life. Your approach is naturally curious and analytical, which gives your solitude, spirituality, hidden patterns and the subconscious a distinctive flavor.
You are likely to notice this most in charity work, unconscious habits and dreams and intuition. When this area is going well, you feel curious and analytical. When it is strained, you may over-identify with mind.
You naturally bring curious and analytical energy to inner life, making you stand out in solitude, spirituality, hidden patterns and the subconscious.
Watch for mind becoming too dominant in this house, especially when solitude, spirituality, hidden patterns and the subconscious feels uncertain.
