Propaganda stands for messages repeated until they feel true. In dreams it is read as noticing beliefs you were handed rather than chose, and questioning where they came from.

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.
