Tetanus, with its image of a locked jaw, is read as being unable to speak or let go. Dream books link it to clenched tension and to a small neglected hurt that grew larger.
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.
