I've always been skittish about elevators, not because of claustrophobia but because they can cause serious injury of death when they fail.  Over the years, I've had a number of nightmares involving elevators and many of them involved elevators that move sideways as well as vertically.  In my dreams this heightened the terror of the elevator ride.  I never thought that there would ever be such a thing, but, how the elevator in my dreams changed direction was never a mental element in these dreams.  Of course, the system in this video is actually a rail car that mounts an elevator, but the experience would be rather the same as in my dreams.
