Being put in the pillory is read as public shame and the fear of being mocked. Dream books take it as worry about criticism or gossip, and about being singled out in front of others.
Has this come up in your dreams before? What was going on in your life then?
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.
