Sky light and sun reflections on water seem like mirror images. Nature gives those on the water daily reflections in the morning and late afternoon. It is then that the sun's rays are angled on bodies of water. All of these photos are angled towards horizons and towards early and late day times. Overhead reflections do not appear because of the light's angle.
Reflections of memories are like that as well. We reflect and reminisce about life when we remember it from an angle - not when it is over our heads.
