I had my bp out and it was the wierdest thing...she made a sneezing sound! I know pretty much everyone agrees that snakes fart, but can they also sneeze????

Okay, so a kinda longer version: She was crawling on my arm and "we" were watching TV. All of a sudden, I hear a sound of a sudden-air-release, and actually FEEL the middle of her body tense for a second (like where her lungs could be-yes I've looked at snake anatomy pics...). I'll admit, at first I was like "Oh S#$%^!!! She's pooping (or peeing I guess) on me AGAIN (happened last night)!!!". Then, I realized, it she wasn't , but she was looking at me wierd. (aka kinda like she was surprised, like when starting to get into a defencive strike position.) Nothing else happend, but we stared at eachother for a few seconds before it hit me...Could she have sneezed???

I'd like to know if anyone has ever had this happen before and your opinion on whether it's possible for a snake to sneeze on you. Thanks!
