What the hell kind of sneeze was this?

I sneezed a few minutes ago, and for a few moments couldn’t breathe through my mouth, swallowed about 10x in succession before taking some deep breathes through my nose, but I just couldn’t draw air through my mouth. What the hell? I felt like I was choking or suffocating or something. (I’m fine now… but damn, that was uncomfortable and a little worrying)
