Susan and her family went to see
this exhibit in Philadelphia and upgraded their tickets to include admission to this IMAX movie. The theatre was set up in extreme stadium style with plush seats and a dome shaped screen which took up the entire overhead space, much like a giant umbrella. Susan happily settled into the air conditioned comfort of her situation and studied the screen before the movie began. It was made of many, many fabric topped panels behind which were the speakers and other things of a technical nature. The lights went away, the titles started and a deep masculine voice began explaining how the giant screen worked. The audience was advised that some may experience a dizzy feeling, but to close their eyes and the feeling would go away. If one had to leave, they were to climb upward to the back of the theatre and once they exited the doors would lock & that would be it.
Susan wondered who would have to leave.
The movie began with a great, swooping aerial view of the desert. It was right on top of her.
She immediately panicked and closed her eyes.
I don't like this.
She waited a moment, it was only a movie, she's sat thru IMAX movies before.
She tried again.
It was too much, she bolted up to the back of the theatre and out the doors.
Claustrophobia: you don't always see it coming.
