A protest is read as a voice raised against something that feels unjust. In a dream it often reflects inner disagreement that has not yet been spoken aloud.
Where in your waking life have you met something like this lately?
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.
