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...
