An autopsy is read as looking back at something that has ended in order to understand why. Dream books see a relationship, a job or a phase being examined after the fact, not a literal death.
Where in your waking life have you met something like this lately?
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.
