It's not really unsovlved. It's called "Photic Sneezing" AKA "ACHOO -- 
Autosomal Compelling Helio-Ophthalmic Outburst".

It is genetic and it only affects less than half of the population. My 
father does it, my sister and I both do it, but not my mother. I can even 
do it by looking at a fluorescent bulb (only when it's on). I do it all the 
time because hey, there aren't too many better things than a sneeze.

looking into the light,
