The Jungian reading
The dying figure usually personifies what that person represents in your psyche. A parent's death may mark your own separation from their authority — a necessary stage Jung placed at the heart of individuation; a partner's death may mark the end of a pattern the relationship has outgrown; a friend's, the fading of the quality they carry for you. The grief is real and worth honoring rather than explaining away: an inner arrangement truly is ending, and the psyche stages funerals for the same reason cultures do.
