Writing or handing in a report is traditionally read as giving an account of yourself. Dream books link it to being evaluated, and to the wish to present your work clearly and be understood.
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.
