Being stalked is read as a persistent worry or an unresolved feeling trailing behind you. When you are the one watching, dream books read it as a fixation or a desire kept secret.
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.
