Dying in a dream rarely predicts anything literal -- it far more often marks the end of a chapter, a relationship, or an identity you're outgrowing, with all the fear that can come from letting go of something familiar. What dies in the dream is usually a clue to what's actually ending in waking life.
The Application of Planets shews what is to come, the Separation what is past. - William Lilly (1602.-1681.)
