Shingles is read as something old and dormant flaring up again. Dream books link it to stress resurfacing along familiar lines, and to past hurts that still ask for attention.
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.
