A goblet is a cup raised for a toast or a vow, and dream books read it as celebration, honour and shared commitment. Its height stands for an occasion that is set apart from the everyday.
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.
