A clipboard is read as checking and assessing, holding a list against reality. Carrying one points to taking charge; seeing someone else with it to feeling inspected.
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.
