Being drunk in a dream is read as a wish to let go of control or to escape pressure. It can also mirror a sense of losing clarity in some part of life.
When this appeared in your dream, what were you feeling?
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.
