Meningitis is read as fear of something serious creeping in fast and unnoticed. Dream books connect it to pressure around the mind, to overthinking and to urgent worry about those you love.
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.
