So I read somewhere that a good way to remember to do reality checks is to do one every time you sneeze, yawn, cough, etc... and this got me thinking... I don't think I've ever sneezed in a dream, lucid or otherwise.

Is it even possible? If we sneeze because our nose gets irritated by something, does that ever happen in a dream?

For me, at least, I know my nose isn't properly modeled by my dreams. Reality checking by plugging my nose and then being able to breathe through it works like a charm, so I'm not really surprised that I've never sneezed in a dream.

Has anyone else?
