Another similar phenomenon is that bright light can cause a person to sneeze. There have been a few times where it has happened to me too, but usually bright light doesn't trigger sneezing for me. https://en.wikipedia.org/wiki/Photic_sneeze_reflex https://en.wikipedia.org/wiki/Photic_sneeze_reflex

It happens fairly often to me, and I've noticed a couple of odd things about it. For one, it almost always causes me to sneeze twice in succession, rarely once but never more than twice. I've also noticed that I have the opposite habit - if I feel like I'm about to sneeze, I often glance over at the nearest light source without even thinking. I also have an incredibly specific form of synaesthesia (or something similar at least). I've never noticed it with anything else, but pinot grigio wines always 'taste' blue to me. It's difficult to describe, but it's just an instant sense of "this is what that shade of blue tastes like" and mentally seeing a flash of that colour. Similar shade to this, but a tad darker: http://www.lcbo.com/content/dam/lcbo/products/084186.jpg/jcr:content/renditions/cq5dam.web.1280.1280.jpeg http://www.lcbo.com/content/dam/lcbo/products/084186.jpg/jcr...

Happens to me all the time and it's annoying (especially when driving). Triggers every time when going outside and sun is shinning. On the bright side, after 2-3 sneezes it goes away.

oh yes. i've always had that. going out of a building into sunlight often makes me sneeze. I've heard that is true for 1 in 3 people. It actually has a reasonable explanation. The optic nerve bundle passes near the olfactory nerve bundle at some point. Its just signal cross talk. God's PCB designer having an off day.

Looking at light helps me sneeze when I feel I'm just about to sneeze but for some reason won't. In most cases the light triggers the sneeze, and I'm not left with the sensation of an un-sneezed sneeze. I started doing this when I read about it somewhere, and I got the impression it's universal. I haven't experienced lights causing unwarranted sneezing though, but perhaps it's the same thing, only some are more sensitive than others.

  nope not universal. https://en.wikipedia.org/wiki/Photic_sneeze_reflex https://en.wikipedia.org/wiki/Photic_sneeze_reflex my entire family does it on my mom's side. when you tell it to someone who doesn't do it they think you are crazy.
