A playing companion of mine always complains that he has trouble hitting the ball when his own shadow is cast across his ball at address. I had never given it much thought, but this Sunday, I played in bright sunlight that was casting very distinct shadows. On a couple of holes, the shadow did not bother me so much as the movement of my shadow seemed to distract me during my stroke. I think he got in my head without intending to do so. I am such a headcase anyway when it comes to golf.
