It is common to dream to communicate with your internal organs because they asked for meeting. This happens when an organ is sick, or more than one organ is sick. The organ sends nerve signals back to your brain, to talk about its problems. Your brain might translate some nerve signals as being pain. Your brain might tell you to seek medical help because the organ complained.
If you have such a dream about your internal organs, you should visit your medical doctor. Fast overnight on the eve of your visit and get some blood withdrawn for your blood test the next morning at your doctor’s clinic. A complete blood test will determine the composition of your blood and show common deficiencies and problems.
