There are many explanations for dreaming of a circle. From the perspective of numerology and common sense of dream interpretation, the following are some possible explanations:
1. completeness and cycle: circles usually represent completeness and cycle. Dreaming of a circle may indicate that your life has entered a cycle or periodic stage. This may be a sign that your life is going back to the beginning, or you are stuck in a repetitive pattern.
2. Unity and perfection: The circle can also symbolize unity and perfection. Dreaming of a circle may indicate that you feel United and harmonious in your personal relationship or career. This may be a positive dream, suggesting that you have found support and mutual trust in interpersonal relationships.
3. Infinite Taiji: In some cultural and philosophical traditions, the circle represents infinite Taiji. Dreaming of a circle may indicate that you have an impulse to explore or think about the big problems of the universe and life.
