The lobby is a waiting place between the street and the rooms beyond. It is read as anticipation, a pause before something begins, or uncertainty about where to go next.

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.
