Surgery is read as deep change that requires cutting something out — a habit, a relationship or a belief — so that healing can follow. Lying on the operating table points to letting others work on a problem you cannot fix alone, while performing surgery suggests you are the one making the hard cut. Waking during an operation is read as being too aware of a painful process. A successful operation is taken as relief after a necessary loss. The dream is a symbol of change, not a medical sign.
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.
