Bad breath is read as fear that your words, or the way you speak, are pushing people away. Dream books link it to unease about communication.
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.
