Conventionally dreams of death point to birth or life changes for the dreamer or people in her life. In modern day life death in a dream can suggest there is a challenge that must be faced.
It suggests to adapt your world view; welcome the challenges and discomfort that comes with change. Remember that with endings come new beginnings.
To dream of your own death is to explore your perception of death, leave your body/ego behind, and maybe explore your spirituality.
