Claustrophobia is the fear of being closed in, trapped in a small space. It is a common phobia.
Many people experience it to varying degrees.
Perhaps in an elevator, or a car in a tunnel or a long plane ride. Yet, the feeling of being trapped comes in areas of our lives that have nothing to do with feeling claustrophobic in small spaces. There are many ways we can feel trapped or closed-in. Some feel trapped at home with ill and aged parents who demand constant care. The catalog of entrapment situations and circumstances is nearly endless.
