Death - that sounds like a symbolism thing that's more than likely caused by something happening in your life. Stress, a change of lifestyle, or maybe even something good (like a new lover or something).

If the former, you need to figure out what it is that's going on in your life and change it. If the latter, you're likely very affraid of losing whatever it is you have. Or maybe a bit insecure about being able to keep it?
