Claustrophobia

Claustrophobia is the fear of having no escape, being in small spaces or rooms, or being confined. The fear is usually most intense in young children. The fear is often triggered due to being locked in a dark room, closet, or even in a box, being alone in a vehicle, or getting stuck in the holes or between bars of a fence. Sufferers would avoid being in a small room (even when lit) (especially without windows), small spaces, vehicle, elevator, crowds, cellar, and caves.

Studies suggest that about 5-7% of all people suffer severe claustrophobia, and it is believe to be more commonly suffered by fat people.
