Claustrophobia

Sitting on an airplane with a feeling of euphoria. The plane disappears, and I am falling, still buckled up in the airplane seat. Euphoria is shattered by terror. Now in a panic, I try to free myself from the seat in free fall. I manage to get the buckle off, but it shoots back into place. I unbuckle again, the seat belt is relentless and once again restrains me. I am still falling, still fighting with the seat belt. I look down panic, the ground so close, I brace myself for impact. I crash into the ground in the middle of a desert like landscape, instead of being mangled by the force of impact I pass right through the ground it is sort of water-like. I am no longer attached to the seat and I try to swim for the surface. I hit a wall, change directions, hit another wall, again a new direction and another wall. As I swim in circles trying to get out it becomes apparent that the box has begun to shrink. At some point, before the box gets terribly small, I wake up. However, I still feel like it is shrinking around me.
