Tall Horse

I had another horse dream last night. I was grooming a group of 20-30 horses and getting them ready for something. When I finished I jumped on one of them and when I went to put my feet in the stirrups I noticed that the horse had grown REALLY tall to the point that the other horses looked the size of house cats at the feet of my horse. I noticed the reins tucked neatly in the saddle and took them into my hands, and then the horse started to move. I was afraid at first and worried that the horse might start to crush the others or start to freak out. Instead the horse was very gentle and conscious of the others and carefully stepping over them and making her way to the front of the other horses and the dream ended.
