Dreaming of being pregnant with twins can symbolize a sense of duality or balance in your life. The twin girls represent two aspects of yourself or your personality that are coming together and growing. The fact that one of the twins is named Kathryn could represent a specific trait or quality that you associate with that name. Being at the hospital for a check up and ultrasound suggests a need for self-examination and evaluation. The positive test result for something could indicate a new opportunity or project that you are excited about. Your mom and sister talking to the nurse could symbolize your inner dialogue and the support and guidance you receive from your family. The healthy babies and growing stomach could represent the potential for growth and development in your life. Overall, this dream may be a reflection of your desire for balance and growth in your personal and professional life.
