To dream of having an illness denotes hopelessness, unpleasant changes, or emotional depression. Illness can be a symbol of your inability to cope with a situation. You see that being sick is the easy way out. On a more direct note, this dream may signal you to pay more attention to your health, especially the areas of the body revealed in the dream.
In particular, to dream that you have some terminal illness or disease implies that you are living in “borrowed time.” The dream is a reminder that life is too precious and you need to make the most of your time every day. Alternatively, having a terminal illness in your dream signifies hopelessness, pain, and self-pity. In what area of your life do you feel this way?
