Arriving on the wrong floor is read as being out of place — at the wrong level of a job, a relationship or your own expectations. Tradition asks where you were really trying to go.
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.
