Feces 
To dream about coming in contact with feces suggests there are certain negative or unclean qualities about your personality that you believe are repulsive to others. You should deal with your feelings and not hide them, regardless of whether they bring you embarrassment or shame. Let go of the negative emotions in life. This dream can also indicate someone in your life who is anal retentive.
To dream that you are unable to dispose of feces indicates that you are not ready to release or reveal your emotions. You tend to keep things bottled up inside.
According to Freud, feces represents pride, shame, economic situations, belligerence, and ownership.
Anus
To see your anus in your dream symbolizes hidden feelings that may be of a destructive nature. Your dream may be expressing remorse, disgrace, or a pessimistic aspect of your personality. Also, the anus can represent your ability to be charitable or miserly. Perhaps you or someone you know needs to be more open-minded and less high-strung.
Constipation
To dream that you have constipation implies that you refuse to accept new behaviors and actions. You are comfortable with your character and personality and see no need for change. You should stop worrying about past issues. Instead, learn how to offer absolution to those who have committed wrongs.
Bowel Movement
To dream about a bowel movement indicates that you are discarding longstanding ways of thinking. It generally means the liberation of powerful thoughts.
