A home altar for the ancestors is read as connection with your roots and with those who came before. Dream books see it as honouring heritage and drawing quiet strength from family memory.
Has this come up in your dreams before? What was going on in your life then?
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.
