Shoplifting in a dream is read as taking what you feel you are not allowed to have. It can reflect guilt, a hidden wish, or a feeling that you get less than you deserve.
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.
