This excerpt is from Psychoanalysis - Interpretation of Dreams
"When dealing with dreams about dying we also have to take into account the symbolism of death. Death is a structural transformation of the being - during the Ego development process we often undergo successive symbolic deaths and re-births: something of us is dying and another thing is emerging. "
And this one from Dream Analysis and Interpretation, doing it!
"Nearly any dream you have that refers to death, dying or attending a funeral, or the like, pertain to change. Most all the time this change is very dramatic and major. It can be change in your life attitude or emotional balance. These types of dreams can also symbolize confronting fear, usually fear of death or change. Since most of use will agree that death is the ultimate change, and many people fear it. Death dreams are generally big changes and should never be ignored. Sometimes they really do signify death! Another possible symbol of a death dream is threat. Whichever suits the dream depends on how well the theme was arrived at. Most death dreams are about major change and not about literal death though, so don't panic if you have one. Just patiently go through the analysis process, and make sense of it."
I will not attempt to analyse your dream, just thought I would add these interpretations of "death" as food for thought.
