If your dreams often feature themes of illness or loss of strength and you are concerned by these, see your doctor by all means; the chances are, however, that you feel unable to meet some internal or external commands in waking life. In your dreams, your unmet goals and high standards are making you ill. But dreams in which you have boundless energy and physical power seem to be telling you that you are capable of far more than you realize. In some cases, as with people who are seriously ill or disabled, dreams of extraordinary energy and good health are compensatory or wish- fulfillment dreams.
If, in your dream, you are weak because you have lost weight, this can suggest concern about body image but it can also indicate possessive, demanding behavior from the people in your life. Conversely, gaining weight and strength may show an excessive need for their approval and a childish need for instant gratification. Finally, if other people are watching either your feats of strength or growing weakness in your dream, this suggests that you are preoccupied with themes of competition. Who or what are you trying to compete with, surpass or vanquish? [1]
