Singing carols is read as joy shared in many voices and the warmth of tradition. Dream books link it to belonging, to memories of seasons past, and to a message of goodwill carried from door to door.
Where in your waking life have you met something like this lately?
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.
