It's rare, but I suspect this happens to all of us if we play the game long enough. In reality, we don't need an Avatar. And through the green, we really don't need to see the ball (to hit it) as long as we have an aiming point. Both are visual aids to enhance our experience by human interface. And like you already discovered, we can view aiming points by other means such as reverse angles and course diagrams...and we can move the aim point from either. When you get into situations like this, take a deep breath, check the lie, distance and wind, adjust your aim, select the spin, pick the club, let it rip and cross your fingers.
