That first one was funny. If I were ever in a situation like that where I knew I was going to be killed, I would taunt my tormentors until I couldn't speak anymore. As they hack off my hand, I'd be like "mothafucka I only used that to beat my meat, this ain't shit dude." As I hear the power drill running, "is that all you have, you pussy ass faggot?" Hitting me in the head with a hammer, "you swing like a bitch." I would ruin the whole experience for them. They may draw out my torture for it, but whatever, at least I get to experience life a little longer, and I'm already fucked anyways.
Guy, listen to the tech on this. That is all I have to say.
Anyways, if you are looking for scary stories, the "creepy pasta" section of the web is probably what you are looking for.
I get ASMR, so I don't know if this sort of room ambience and movement is something you can appreciate. Both aren't 3d sound, but, anywho... maybe we've done the same blotters or something?
