The Salt of the Earth

I like a lot an image from a short story by JG Ballard (is it "The salt of
the Earth"?), and I think it might be reused in a Kult game:

Someone awakes every night because of a tiny sound: it's like the sound of
waves from a distant sea, breaking on the shore... If he gets to the window
and lift a little the curtain, he sees the valley progressively flooded by a
ghost tide: an immaterial water shedding a faint eerie light, like a foam of
light which comes up and up... Finally, he is submerged by this ghost water,
and there is strange lights in his room, like underwater glimmer and moving
aquatic shadows... The real sea however is several miles removed from his
house, and never climbs in the valley...

But each night, the phantasmal sea comes back... Each night it is more real...
When the ghost sea comes, he slips out of his bed and goes out of his house
to see it coming and submerge everything in the valley, the ghostly surface
far above his head (but he has no trouble to breath). There is a faint odor
of salt floating in the air.

Suddenly, a night, the water becomes real, and he his under a real water
from a real ocean... He has to swim to the end of the valley to avoid being
drown... But the whole landscape changed, and nothing is like it used in the
valley...

In the Illusion, the man just disappeared...

I think of two Kultish interpretations for this:

- either the Veil is tearing apart, revealing the shore of the Metropolis
Primal Sea; if we set the house in the suburbs of a big (Californian?)
city

- or Gaia is invading a Valley near a portal (if we set the house in a
wild place which is to be swallowed by Gaia)
