Basic overview: What is Therianthropy?

Therianthropy is a spiritual belief that your soul is that of an animals or that your body is shared with an animals soul or you believe you were an animal (or anything that was once alive that is non-human) in a past life. Sounds complicated, right? Well it's not fake. It's a real belief and it's growing slowly throughout the world. I am a person with this belief. This will be a recorded pile of my experiences, opinions, beliefs and so on for this topic.
