Closeness with another person in a dream stands for the wish to be truly known. Dream books read it less as about that person than about how much of yourself you are ready to let near.

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.
