What's the scariest story you ever read? I read all sorts of disaster/true crime/horror stuff, but the one story that gave me the most willies must have been Harlan Ellison's "I Have No Mouth and I Must Scream." (If you don't know, this is the piece the Terminator series bounced off of.)
I read it first when I was a kid. I think I was ten or eleven. I was busily devouring my dad's stash of SF novels, a lonely kid who loved the geewhiz mindboggling but rational escape early and mid 60s SF was filled with.
It was in a collection of short stories. I don't remember the name of the anthology. But I remember feeling the helplessness of the group of people who were caught in this machine as toys to be tortured, and the fate of the narrator. Must have represented perfect hell to me at that time, cause when I bring back the memory of my reaction, I still get the willies.
Good piece of writing, that.
