Traditionally, emotions have been thought to be centered in the abdomen, so a dreaming about your abdomen can be a sign that you are experiencing strong emotions.
If your abdomen is injured or you are feeling pain in your abdomen in your dream, you could be harming yourself by repressing difficult emotions.
Your dream is telling you that you should accept these emotions and take steps to handle them.
A dream about an abdomen can also reflect thoughts about pregnancy.
