How come we don't sneeze while we sleep?

Answer 1

These are all hypotheses, so forgive me if they're wrong.

First, because breathing patterns are different when we sleep. Second, because sensations are decreased when we are asleep, and like vomiting, sneezing, though an involuntary reaction, sneezing is initiated by a "feeling". No feeling of sneezing, no sneezing. Third, motor neurons are less active when we are asleep, so as to decrease our ability of doing tremendous sudden muscle work such as laughing and sneezing. Fourth, because mucus production is greater when we are at sleep.

Answer 2

I think the urge to sneeze disrupts sleep and wakes you up.

I have awakened in the night with the need to sneeze but as far as I know have never sneezed in my sleep.
