Everything was reflected, but there was a mathematical science behind that, which was that any object would be in a constant or moving position. If the object was on any one side at the time of reflection and a focus was available, then the shadow would reflect on the earth.
In my childhood days, some friends were playing with me and said, This is the devil's way of following you. Be careful, but at the time I didn't know this was a mathematical science reason to reflect any object.
