Daemon?

I haven't read these books, but I think I'll have to. According to this story, a person's soul lives outside of their body in the form of an animal spirit. It's not fixed when you are a child, but as you settle into the person you are going to be, so the animal settles on a form. Apparently I'm a raccoon. I'm sure the correlation is a stretch, but I think that this would probably be the form of my patronus (had I a wand and a really happy memory to hand).

What do you think?
