The jester hat is read as humour, play and the freedom to say what others will not. Dream books also see the mask of the clown — laughter worn over a serious truth.
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.
