The top of a bus represents the top of your body – your head / mind. An open top bus is asking you to open your mind to something new in your life. If you have recently ‘made up your mind’ about something, you are being asked to think again. If something has come your way and you are dismissing it, you are being asked to think differently. Rain coming into an open top bus asks you to open your mind to letting life in while on your journey.
