Question

Why sneezes will come?

Answer 1

A sneeze, or sternutation, is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. ... The function of sneezing is to expel mucus containing foreign particles or irritants and cleanse the nasal cavity

Answer 2

We sneeze to expel out the mucus which contains dust particles trying to enter out nasal cavity...

Hence we intend to sneeze when dust particles enter our nose....
