A trapdoor opens onto what lies hidden beneath the floor of everyday life. Dream books read it as a sudden way into the unconscious — or, when you fall through, a fear that the ground could give way.
Has this come up in your dreams before? What was going on in your life then?
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.
