Claustrophobia

Claustrophobia was the fear of enclosed spaces. April MacLean was not aware that Charlie Smith was claustrophobic until Andrea Quill locked them in Class B3 for detention. When the classroom was taken out of time and space and Charlie found that there was no escape, he suffered a panic attack because of this. (TV: Detained)
