In real life, gangrene occurs when tissue dies. An infection or lack of circulation can harm the tissue. To dream of a specific part of the body in a condition of gangrene would symbolize a lack of flow or balance in the area that the body part represents. For example the arm would relate to a balance between giving or taking. On the leg - it can symbolize how you are moving forward and whether all of your needs are being met. Gangrene near the chest area can relate to cutting yourself off from feelings. On the feet, you may not be feeling empowered. You might also explore the association with 'green' as a message about achieving health and wellness. See also Inflammation and Decay.
