Sweeping ancestral graves at Qingming is read as caring for roots and keeping memory clean. Tradition takes it as respect, duty and a spring renewal of the bond with those who came before.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
