A sonic boom is read as a sudden jolt — news or a change arriving before you could hear it coming. Dream books link it to breaking through a barrier, with all the noise that brings.
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.
