A relative in a dream is read as a trait or pattern you share with your family. Dream books link the figure to inheritance, loyalty and how your roots show up in you.
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.
