When every link to the outside world is severed, time has no meaning. It ceases to exist other than as a dull memory, a vague recollection of what a minute used to be, an hour, a day. Sealed up tight so far beneath the ground, every single second was stretched out almost to infinity—each one a vast and empty abyss where time used to reign, an ageless aeon barren of significance and consequence.
When every scrap of light and sound has been taken away, reality has no meaning. It too ceases to exist, for what is reality other than the cumulation of senses—images witnessed by our own eyes and the noises that enter through our ears? But when all those senses are starved, then the real world fades away like the last frantic gasp of a television program when the set is switched off.
And when reality goes, sanity has no reason. How can your ability to behave in a normal and rational way still exist when nothing normal or rational remains? As soon as reality breaks, as soon as we are separated from the physical world, the cracks begin to appear in our minds. And through them seeps the madness that has always been there, flowing into your skull like a liquid nightmare.
