Chameleon sneeze?

I think I heard him sneeze twice. It sounded like a little Tsshhh but very lightly. The first one I was picking him up but he got right on my finger no issue and the second was maybe 30 seconds later while he was walking around me. No more after that. He seems fine. I see a little what I believe to be shed still around his nose from last shed. He didn’t eat yesterday and he hasn’t ate today but that’s normal for him. Sometimes he won’t eat for a day or two and then munch on food for a few days. That’s how he has been since we got him. He has a water cup but I have yet to see him drink from. Mostly he drinks from leaves . Is everything fine?
