Your fellow really does sound more and more like my old fellow, Shadow. I could de-sensitize him all day with plastic bags, etc. As long as the object was "under my control", he would stand there and go to sleep. But if he thought **I** was not the source of movement, then it became its own entity, and morphed into a scary, horse-eating object.
I could see this happen with a bag on a rope. At a certain distance, he would lose the connection between me and the bag, and it would then be "alive". Under that distance, he could see that I was causing the bag to move, so it wasn't scary.
With Shadow, sacking out had definite limitations. I started when he was just a foal, but it never 'took' because of the way he viewed the 'game'. He knew I wouldn't hurt him, but even at 25, a gum wrapper blowing in the wind was going to EAT HIM.

Your discourse here does not represent what my horse does. Mine spooks only in safe situations (safe for him) and sometimes there is nothing there at all. I truly believe he does it for entertainment value. He had training over a woven blue tarp in an arena, and he learned to walk carefully over it. On the outside, if a blue tarp is sitting out in plain sight, it's a big horse-eater.
