Bed rest is read as an order to stop and recover. Dream books take it as the body and mind asking for a pause that you may have been refusing to take.
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.
