Family in a dream is read as roots, identity and the patterns you were raised in. Dream books take the mood among family members as a reflection of how you carry those bonds today.
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.
