This is so specific, but almost like I smell the inside of my nose or bad breath if I take a big sniff when I yawn at the same time
I don't get it regularly. Or even if I just sniff in general. Just sometimes when I yawn. Even if I force a yawn
The other thing is it rarely if ever happens outside, only at home. No other symptoms and I know the bad ones. It doesn't even happen all the time
I'm mostly writing this out to show myself how bad it sounds, because in my head it sounds severe.
