I can't play over an hour to Amnesia.
I happenned to have a nightmare once, just after playing and that was of course about a monster chasing me and roaring "right" and "left" each time I changed paths. I managed to run so far I didn't hear it anymore so I thought "all right, I'm safe" and then I hide behind a barrel. After 2 seconds I look over my shoulder and THERE HE WAS ;pvekrpv omg and then I woke up
It reminds me of Silent Hill 1 and 2 because I never felt or had such an experience since those games (even Penumbra was not so hard on me).
