Dream about having a deadly illness suggests important transition in life or the end of a negative habit. You are going nowhere. You do not know how to deal with your feelings. The dream points to someone who is behaving crazily. You are currently finding yourself in a situation that you do not want to be in.
Having a deadly illness dream is a message for your limited perspective. You are being told that you were never loved. Some situation or relationship is not going smoothly in your life. This dream hints temporary trouble due to some misunderstanding of your action and conduct. There is someone or something that you need to rid yourself of from your life.
If you dreamt about having a deadly illness:
Not much will happen until you decide to give up a few vices that have a serious effect on your well-being. Realize that if there are certain things that control you, you don't have complete control over your life. Try not to fight this truth. Simply accept that these things exist in your world, and understand that you can coexist without having to surrender to their power.
