Mercury Retrograde in the 12th House
Mercury retrograde in the 12th house is a natal placement: you were born with Mercury moving backward through the house of solitude and the unconscious, so your deepest thinking happens out of sight, even from yourself.
Modern
The 12th house is the unconscious, solitude, spirituality, and what stays hidden. Mercury When a planet appears to move backward through the zodiac from our view on Earth. Its energy turns inward, slows down, or revisits old ground rather than pushing ahead. here from birth gives you a mind that does its most important work in private, in dreams, in quiet, in the spaces between words. Thoughts surface in their own time, often arriving fully formed after you have stopped chasing them. You may find it hard to explain how you know things, because the knowing came from underneath. The gift is a deeply intuitive intelligence with access to what others overlook. The work is bringing some of that inner world into daylight, so it does not stay sealed away.
