Haggling over a price is read as negotiation in a relationship or a decision: what you would give up and what you insist on keeping. Dream books see in it the wish to come away feeling you were treated fairly.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
