Driving in fog is read as confusion about where things are heading. Dream books link it to slowing down, paying attention to small signs, and waiting for clarity before making big moves.
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.
