If you dream of organ cleansing, it can mean your body is sending you a message. Internal organs which are not functioning well or have problems, may send signals to the brain. The brain then invents a dream to call attention to the problems. You might be having a medical problem. If you think you need a physical check, visit your doctor to get their opinion. If there is nothing wrong, ask for the medical expert to advise you on the practical probability of doing a detox diet for a day, with vegetables and fruits.
