A sweatshirt is read as relaxed, everyday warmth. Dream tradition links it to rest, informality and the wish to step out of a role and simply be comfortable.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
