Washing your things in public is read as private matters being sorted where others can see. The laundromat also stands for patience, routine and waiting for something to come out clean.
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.
