A winery is where fruit becomes something richer with time, so dream books read it as maturing, patience and the reward of slow work. It also carries the old sense of abundance and shared celebration.

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.
