I find that in bright light I sneeze, especially in bright sunshine.
why does this happen? is this something everyone does or just me?

Many people have this reaction--I do too.
It's thought to be caused by some of the nerves from your nose getting "crossed" with the nerves that come from your iris. Bright light hits your iris and it sends a signal to your brain that it's irritated. Somewhere along the path the signal gets crossed into the nerve from your nose, and your brain gets a message that your nose is irritated--provoking a sneeze.
It's kind of like that game "telephone" where the original message gets transformed as it travels.
Interestingly, most people sneeze a set number of times when they go out in sunlight--it's two for me. I had an ex-girlfriend who would never say "God bless you" at the first sneeze, she'd just look at me waiting for the second one...

Of course we all do that! Silly!
The question is, does ZZ Top sneeze when looking at bright light. They never take those dang shades off.

I do if I have a trapped sneeze i look on the solar to get it out. apparently its led to with suggestions from crossed mind paths recognising the uncomplicated in the incorrect way and causing us to sneeze. i concept everyone did it. apparently its genetic I merely had a glance it really is sensible as my relations have it.

up to 25% of us of do
this is because of the close association between the eye's 'optic nerve' and nerves that stimulate the sneeze reflex
this is known as photic sneeze reflex
also called Autosomal Dominant Compelling Helioophthalmic Outburst Syndrome (Known as ACHOO)

I do, and sunlight between trees flashing by if I'm in a car or bus puts me into a trance!
