Mercury in the 12th House

Mercury in the 12th house indicates that your thinking is strongly influenced by unconscious memories and habits stemming from past experiences. You base your decisions on feelings rather than reason. People with this position are likely to be secretive about what they think and feel and like to work in seclusion. Be open to the possibility that you may be living in a dream world. You lack self-confidence and may at times have trouble expressing yourself. Nevertheless, you are good at analyzing other people's problems. There is an interest in the psychic realms and very active imagination and subtle mind. If your Mercury is close to the Ascendant it will take on a first house feeling, so you would be very communicative and less introverted. With difficult aspects you may have had trouble relating during early education resulting in reading problems or other mental blocks, or you might have had an extraordinary childhood; perhaps you were raised in a foster home, orphanage or boarding school.
