Oh the absolute worst one. Everyone gets locked in eternal solitary confinement with no lights, no touch, you don’t know if your whole body’s gone numb or there just isn’t even ground beneath your non existent feet. When you try to touch yourself there’s nothing there and yet you are painstakingly aware of somehow existing. Every nanosecond feels like an eternity and you’re constantly being flayed, drowning, burned alive, raped, and jump scared by the worse horrors you never imagined could possibly exist. You never ever pass out or sleep or have any form of respite except to give you context to your indescribable suffering. You hold only so much memory as to know there once was a time so much better than this, and you never figure out that you’re dead/immortal because that might cause you to become psychologically numb to it, so even that you don’t have going for you.
Anyways, yes, the worst one, that one. I choose that one.
When I have trouble concentrating on what I’m reading be it for work, education, or pleasure, as long as I’m in a space that allows for it, I’ll read aloud. It’s surprising how much more enjoyable/bearable this makes it.
Also, if fiction, you can practice your acting skills during character dialogue, which can be fun/mildly embarrassing.
