An egg cup holds something fragile upright, and dream books read it as small, careful support for a beginning. It can also recall childhood breakfasts and simple routines.
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.
