The bidet belongs to private care, so it is read as the wish to feel clean and composed. Dream books link it to washing off a sense of embarrassment.
When this appeared in your dream, what were you feeling?
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.
