I've always had my horses read after an accident and I just give her my horses name and she recites the entire accident to me, (I didn't tell her any details, literally just my horses name) and then tells me where my horse is sore, what he is now afraid off, and pretty much everything else. She is always 100% correct. And is done all over the phone. She isn't even with the horse. So I totally believe, I mean there will for sure be fakes out there, but they do exist.
I thought it was a load of crap until a friend who is an animal communicator had a session with my new horse and everything he "told" her has turned out to be true. There was no other way she could have known some of the things she told me about my horse. As long as the price is reasonable I'd do it, at least for the entertainment value.
