Embarrassment in a dream is read as worry about being judged for a small slip. Dream books link it to self-consciousness and to a wish to be accepted as you are, flaws included.
When this appeared in your dream, what were you feeling?
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.
