Dream about using toilet in public is sadly an alert for your desire to help those headed in the wrong path or in the wrong direction. You need to indulge in life and devote some time to leisure. Your friend is not being supportive. Your dream states your unexplored, underdeveloped, or undisciplined power. Something or someone in your life is trying to squeeze every bit of energy or information out of you.
Using toilet in public dream points at a person, situation, or relationship that you want to distance yourself from. You are ready to rid yourself of all that extra baggage that is holding you back. You have been holding back some of your true feelings for too long. This dream is a symbol for your need to sit down and take time out to contemplate a situation before proceeding. You are overly dependent on your family.
If you dreamt about using toilet in public:
You are being even more underhanded than usual, and a whole shoal of red herrings are out in force to confuse the signals that you are trying not to give someone. The game is already up!
