A paycheck stands for recognition: what your effort is felt to be worth. A short or missing one is traditionally read as feeling undervalued, a generous one as feeling seen.
When this appeared in your dream, what were you feeling?
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.
