What does it mean when you dream your husband with cancer dies?

If your husband actually does have cancer in real life, the dream represents your subconscious mind's attempt to prepare for very real possibility of his death. This is a very normal function of self-preservation. On the other hand, if your husband is not a cancer patient, then you may be more concerned about his health than you realize. It may be that you believe that he is not taking care of his own health the way that he should.
