Alcoholism in a dream is read symbolically as a habit that has started to steer, or as a way of escaping a feeling that keeps coming back. Dream books treat it as a question about control and relief, not as a judgement of the dreamer.
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.
