Trepanation, the old practice of opening the skull, is read as the wish to let pressure out of the mind. Dream books link it to wanting relief from thoughts that feel trapped and to radical ways of seeking it.

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.
