A commission is read as reward tied to results, payment that depends on what you bring in. Dream books link it to ambition, performance pressure and the value of your persuasion.
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.
