School is read as the place of lessons and comparison. Being back there as an adult is a classic dream, traditionally about being tested or measured again.

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.
