Why does my nose twitch while angry?

Normally it only happens when I’m like 7+ out of 10 angry but it sometimes happen when just agitated or an angry-annoyed too. 
I’ve never had it happen until this past month and it happens quite frequently whenever it starts. 
It happens almost every time I’m a 7+ out of 10 angry
And no silly replies, I’m actually looking for an answer please
