A misspelled word is read as a small error you are anxious about, or a fear of being judged on details. Dream books also see it as a sign that something was said not quite as intended.
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.
