Some people only sneeze once. Like me but my sneeze is a scream. I sneeze from my throat so that is probably why I only sneeze once. When you sneeze it is normally because your nasal passages are filled with mucus and your body is trying to remove it. When you sneeze multiple times it is just a reaction. Have you noticed if someone tickles your nose or you look at the sun you sneeze? After one sneeze some people have that tickle feeling so they sneeze repeatedly.
