Are these abnormalities actually normal?

I have noticed that my body is really asymmetrical. I was wondering if there was any underlying meanings for this. First my pupils are entirely two different sizes. Second, my thumbs are also two completely different sizes and shapes. And lastly, my dimples are in different places on my face. One is in a "normal" spot where most people have them and on the other cheek its around an inch from my eye. Does anyone know any reasons for each of these? I also don't think that these are genetic considering I am the only one in my family with them.
