Having to repeat a school year is read as feeling stuck or sent back — a lesson that seems not to have been learned. Dream books see it as frustration with a cycle that keeps returning.
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.
