An architect stands for design and the plan behind a life. Dream books read it as the part of you drawing up what you want to build, long before the first brick.
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.
