Being bullied in a dream is read as feeling powerless before someone, or before your own inner critic. Tradition sees it as old hurt resurfacing and the wish to stand your ground. A bully from school appearing years later is read as a past experience echoing in a present situation. Standing up to the bully is taken as growing confidence; running or freezing as feeling cornered. Being the bully yourself is read as frustration or anger that needs a fairer outlet. Watching someone else being bullied is read as discomfort with an injustice you have noticed. It can help to ask who or what makes you feel small right now.
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.
