Being drunk in a dream is read as loosened control — relief from holding everything together, or worry about losing your footing. Seeing someone else drunk is traditionally taken as unease about how much you can rely on them.

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.
