ELI5: Is it possible to sneeze while sleeping? If not why?

I know we don't remember what we do when we sleep...so I've always wondered if people sneeze while sleeping...and if not why?

No, at least not during REM sleep, as motor neurons aren't being stimulated and reflex signals to the brain kind of shut off. It is possible to wake up for the purpose to sneeze and fall back to sleep though, and if that happens you likely won't remember it.
