Brushing lint from clothes is read as tidying your image before facing others. Dream books also link it to removing small traces of a situation you want to leave behind.
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.
