one line from House of Leaves in particular sticks with me, a quote from a (fictional) french caver:
“Darkness is impossible to remember. Consequently cavers desire to return to those unseen depths where they have just been. It is an addiction. No one is ever satisfied. Darkness never satisfies. Especially if it takes something away which it almost always invariably does.”
I used to be into caving. There's something transcendental about complete darkness. Not just the merely dark of an overcast, moonless night, but the truly black. Caves are the only place I've seen it. No visible-wavelength photons beyond those made by radioactive decay, maybe.
It's uncanny. Humans aren't built for it.
Most people begin to gently hallucinate after anywhere from a couple minutes to a half hour.
@starkatt Seems like an okay thing to experience for a few minutes, after that probably not so much.
.... I am such a child of the sun.
Also, have you read The Skook? It's... quite dated now in several respects, but it deals with a guy trapped in a cave for a very long time without any light. And hallucinates, or doesn't, several things.
@starkatt Huh, nobody's selling ebooks of it... seems probably not. n..n;
@Soreth I have not! Is it available online?
