I'm sorry but I don't think you are a goat. It sounds like your soul was a goat in a past life. Maybe this is past life regression and you are remembering what it was like to be a goat. I'm not going to share with you my personal beliefs on the matter, but some people do believe that souls can be switched between bodies. You weren't very specific in your question. You should edit it to say when exactly you starting being under the impression that you were a goat. Otherwise, you might need to visit a psychologist.
