You may be Claustrophobic if you find yourself in a tight space, like a closet, submarine, or car trunk and you are short of breath and trying to get out. Of course, you may be a spy and that's why you are in said closet/submarine/trunk, but if you are having a panic attack, you may need to reassess your chosen profession and consider a job at a check cashing facility--which undoubtedly would give you the same thrill, yet not force you into a tight space where you begin screaming, "GET ME OUUUUUUUT NOOOOOOWWWW!!!!!!"
I, myself, am a non-practicing claustrophobic. Non-practicing because I am not foolish enough to get myself closed up in a car trunk or submarine without a handful of Valium. Of course, the one time I was put in a car trunk I was in the middle of unraveling the iron curtain in 1989 (yes, I was a teenage spy--ask anyone at North Jr. High) and thanks to my trusty Swiss Army knife, that trunk and I didn't have time to get to know each other very well.
I am such a non-practicing Claustrophobic that I don't even really even like to think about car trunks, bank vaults, or deep sea submersibles because I break out into a cold, clammy sweat...which is why I handed in my spy credentials at 16 and pursued the stage instead.
What makes you feel claustrophobic?
