A facade is the face a building shows the street. Tradition reads it as the image you present — and a facade with nothing behind it as the fear that appearance is all there is.
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.
