If you dream that you suffer from constipation, you may be holding onto something that has a negative effect on you. This could be a belief, an attitude, a habit or a relationship. You have become very attached to it and in real life, you may be denying the fact that it is harmful to you.
If you dream that you are constipated, ask yourself if there are any negative influences in your life that you could eliminate. Are you retaining old behaviors because they are comfortable to you and it is hard for you to change them, even though these behaviors are harmful?
A dream that someone else is constipated can mean that you think that this person is stuck in a pattern of negative behavior and will not listen to helpful advice.
A dream about constipation may also have to do with a fear of failure. You are afraid to try to take on a new task because you think you will not be able to complete it successfully.
