I know there is. I have only ridden one horse who was that way.
I know with the mare I have in mind, was a really misunderstood horse by riders. No one trusted her and would always try to over-control her and try to decide everything for her.
When I came around and started riding her I realized if you let her be, she would carry you and care for you over everything. You just had to give her head, give her some rein and let her help you. She was the best horse I have ever ridden. For a year I had to share her with another rider, a girl my age. That rider had a different riding style which was proper but that mare could not stand her.
I think with some horses they might become one person horses because of History of abuse or mishandling?
I have only met one horse who was that way, so my guess will be as good as any other.
