Awe in a dream is read as meeting something vast and humbling. Dream books link it to wonder, to a wider perspective and to feeling small in a way that is freeing rather than diminishing.
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.
