A shipwreck is traditionally read as a plan or relationship that ran aground. It describes a feeling of collapse, not a coming event, and survivors on the wreck stand for what can still be salvaged.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
