A straw hat stands for summer, honest work and simple pleasures. Dream books read it as a wish for slower days in the sun, close to the land.
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.
