As for my own dreams, they have been pretty vivid, too. Regarding my health, I dreamed that my husband told me that I had two months to live after the operation. But I told him no, that wasn't true. My grandmother (deceased) had bought me more time on earth.
In a previous dream, I was making a bed to get into it as I told my mother I had cancer, but my grandmother quickly got into the bed in my place.
When I woke up, I knew that she intervened somehow. We'll see what my test results say. Oddly, I now can sleep on my left side without feeling any discomfort though.
