When you bow to another person in real life, you are acknowledging their superior status, so if you are bowing in a dream, it is a sign that you are feeling inferior to someone else.
You may feel that someone in your life could perform a task better than you could, or that they would find it easier to achieve a certain goal than you would.
A dream that you bow to someone can be a message that you need to recognize the knowledge and abilities of others. You may need to learn that sometimes it is better to ask for help from others than to always rely on yourself to get things done.
A dream that someone else is bows to you symbolizes a desire for recognition.
