If you dream of having diarrhea, then it shows the lost control of your own life. Perhaps you are no longer capable of dealing with the issues and troubles, therefore you have a diarrhea. On the other hand, the dream could be interpreted as the necessity to let go some things as soon as it is possible. There are many negative thoughts, emotions or people that must be removed.
