In dreams slavery is read symbolically as a total loss of freedom — being bound to work, a habit or another’s will. Dream books treat it as a call to look at what holds you, with respect for the real history behind the image.
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.
