The pointed dunce cap stands for public shame over not knowing enough. Tradition reads it as an old fear of being labelled, often louder in the dream than in waking life.

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.
