Mercury in Pisces
Mercury describes your relationships, your communication skills and the way you relate to the external world. However, other astrological elements also influence these areas. The sign your Mercury occupies is significant only if Mercury is part of your planetary dominantes. In your chart, Mercury is in Pisces. You are connected to the world through your intuition. Contacts are established, and broken up, according to your sensitivity. Your perceptiveness is amazing. You soak into your environment in order to grasp its subtle games and you feel that you know things without learning them. You assimilate them unconsciously and you very sharply pick up hints and unformulated thoughts. Some sort of sixth sense.
