Dreaming about your father-in-law is usually a indication that a family gathering is approaching fast, and that you need to relax. Don’t sweat the family gathering if it is troubling you because even if people are judging you, they don’t really know the real you. It is a time to relax instead of worrying about the small stuff. Sooner or later, your dreams of things that matter will replace your father-in-law’s image.
