A beach ball is read as carefree summer play, light and easily carried by the wind. It may stand for joy that needs no effort, or for something drifting off before you can catch it.
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.
