I had read something a while ago about how a percentage of the population sneezes when looking at the sun or a bright source of light, and this brought to my mind a slightly similar but oddly weird thing I notice in my dad and myself, for which I couldn't really find any good explanations for.
My dad has this thing where he'll sneeze a few times after eating a really delicious meal. Infact we sort of joke that the more times he sneezes, the better his meal was, and he seems to concur. Furthermore, my mom likes to joke that whenever she cooks, he never sneezes, and I sort of agree with this because my mom's cooking sucks haha (fuck u mom)
I have this thing where, whenever I open a porn tab specifically in the evening, I sneeze once. It's really weird and fucked up but I swear everytime it's dark outside and I go on xvideos, I sneeze before I get a chance to select a video. This doesn't happen when I jerk off without porn or when I jerk off with porn during the daytime, so my guess is that it's some sort of association with the opening of the porn website that makes me sneeze. I wish I was joking here.
I also have this thing where, after a cup of coffee, I will sneeze a few times and my nose will get a bit runny, but this often passes after 5 minutes of having finished the cup of coffee.
