A god of death is read as the guardian of endings and transformation, not as a threat. The dream reflects a major change, and the need to let one phase go so another can begin.
When this appeared in your dream, what were you feeling?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
