Every time i'm in a dark or dimly lot place and then walk into the sun i sneeze. Why?
Maybe because you are allergic to some kind of substance that is present outdoors.
I'm 99% sure that that's just natural. It happens to me a lot when I walk out of school on a sunny day after being in the school for a while
It happens to me too. I don't know, so... aliens.
You could be allergic to the sun. My cuz. Is.
The "Scientific American" has an interesting article on the subject ~http://www.scientificamerican.com/article.cfm?id=looking-at-the-sun-can-trigger-a-sneeze
