A hoodie is read as comfort with a place to hide. Dream books take a raised hood as a wish for privacy or anonymity, and a worn one as ease in your own skin.
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.
