A great-grandchild is read as the far future of a family line. Tradition takes the dream as reflection on lasting influence and on values that outlive a single lifetime.
Where in your waking life have you met something like this lately?
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.
