Being bullied in a dream is read as feeling powerless before a person or a pressure. Old hurts from school years often return in this shape when something similar stirs in adult life.

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.
