Introverted Claustrophobia 

When an introvert is a large crowd and feels as if everyone is closing in on them.

Feeling overwhelmed or stressed in crowds or loud noise.

During that concert Nancy felt as if she had introverted claustrophobia.

claustrophobia 

Fear of being in enclosed spaces. Not necessarily small spaces, although many claustrophobic people don't like these much either. The main issue is being trapped in somewhere you can't get out of easily. Claustrophobic people may avoid or feel uncomfortable in situations like flying in a plane, being in the middle of a crowd, or using an elevator.

Friend: Now we just take the elevator up to the ninety-seventh floor...oh, I forgot. You've got claustrophobia. Better take the stairs then *sigh*

Me: Actually, like many others with claustrophobia I still use elevators, because we don't let it control our entire lives.

Claustrophobia 

Fear of Santa Claus

Little Harry took one look at the bleary eyed old geezer with a white beard and did a runner. It was a bad case of traumatic claustrophobia.
