Marking the anniversary of a death is read as grief returning in cycles. Dream books see it as remembrance coming due, and as a time to honour someone still loved.
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.
