When the whole family is gathered in one place, dream tradition reads it as your sense of roots and of where you stand among your own. The mood of the room is taken as the mood of those bonds.
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.
