Horses communicate in a silent language; not only with each other, but also with us. Humans were all born with the ability to communicate using this silent language, but once we verbalised at a young age, it was basically forgotten.
My abilities in this language were reawakened over 15 years ago when animals, including horses, began to openly converse with me. How is this possible you may ask? Well, it is an ancient telepathic communication.
