Intense Mirror Question

Imagine this: Let's just say there's a sphere, and on the inside of the sphere, a layer of mirrors were on the walls, like wallpaper. I have 3 questions:

1. If there was a head, floating perfectly in the center of the sphere... What would all of the reflections look like?
2. Would our brains be able to percieve what it would look like?
3. How would the mirror make the reflection of the head (based on question #1) Extra Question 4) If I asked any stupid, obvious questions, or, I messed up some of my grammar... Could you not comment on it?
