A teacher stands for learning and being judged. Dream books read the figure as a lesson life is setting, or as your own inner critic; a kind teacher points to guidance and growth. A strict or angry teacher is linked to fear of failure or of not meeting expectations. Being a teacher yourself stands for sharing knowledge and taking responsibility. Meeting an old teacher is read as remembering a lesson from the past that applies again. It can help to notice which part of your life currently feels like a test.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
