If your dream shows you that you’re tired, it is likely a continuation of your waking hour self. If you are exhausted, mentally drained or emotionally unfeeling, then it is time for you to take care of yourself. You can’t take care of other people or tasks until you are well enough to function. Eat proper meals. Drink fresh water. Sleep early every night. Take short breaks by walking around indoors or outdoors. Take joy in nature. You’ll find that you won’t get another dream about yourself looking very tired. A dream repeats as a recurrent dream when the issue is present. When you’ve dealt with the prevalent issue, then you dismiss the problem.
