Cyberbullying in a dream is read as feeling exposed and judged by many at once, with no door to close. Tradition reads it as hurt or shame from waking life, not a sign of what is to come; if it is happening for real, telling someone you trust can help.
Has this come up in your dreams before? What was going on in your life then?
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.
