A wasteland is read as a feeling of depletion — a part of life that seems used up or neglected. Dream books treat it as a picture of how something feels now, not as the end of the story.
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.
