Yokai are the strange spirits of Japanese folklore, from the harmless to the eerie. Dream books read them as the odd, unexplained sides of life that defy neat explanation.
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.
