The London Underground system, and subways the world over, are technological wonders used by millions of people daily. Yet descending beneath the surface of the earth is subconsciously regarded with unease. Travellers may mask their symptoms of anxiety by conforming to acceptable forms of social behaviour in public.
But in our own underground of the unconscious, stress and anxiety are culturally embedded.
Fear of the underground in general, not just travelling on the subway, seems to be a collective cultural anxiety.
In many societies these regions are known as the Realm of the Dead, Hades, Hell, the Underworld - a place from whence there may be no return.
