Struggling to say a word correctly is read as worry about how you come across to others. Tradition sees it as the gap between what you mean and how it lands.
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.
