Cancer Dreams. When Do They Stop?

I keep having these weird cancer dreams they seem so real they keep waking me up. After getting the cancer free biopsy results I still had a horrible dream that I was dying from cancer. People say it is my biggest fear. You would think after going through breast cancer that my fear wouldn't be as bad as before. Cancer is a scary thing to go through and it must be on my mind all the time even when I sleep. It's 2 years now since the breast cancer and I'm still dreaming about dying of cancer. So many of my family have been lost from cancer. I wish the cancer dreams would dissapear for good.
