What Is the 12th House in Astrology? The last house on the zodiac wheel, this house is responsible for some seriously heavy stuff. It's linked to nebulous rather than physical concepts, like the subconscious and the imagination, plus paranormal energy. But no need to think of it as spooky — remember that it's ruled by the sensitive and intuitive Pisces, which makes it a great house for introspection. Image Source: Pexels / Andrea Piacquadio
