I bet you’ve never sneezed while sleeping. Thank about it… it’s never happened!
The reason is that our brain actually shuts down the ability to sneeze while you’re sleeping. If for some reason you get some dust in your nose or something physically makes you sneeze your brain will wake you up first. But other than that you’re brain is smart enough to send a signal to make sure you get those precious Zzzzz’s without grabbing the tissues.
