Things that would have made Amnesia scarier

[PvtLastClass]

While the immediate moments a lot of people are suggesting would in fact be pretty freaky, they have one main problem; they are too "designed". 5 seconds after the player finishes that moment, it would be pretty obvious to them that that was a very deliberate and constructed attempt to scare them, remind them that what they're playing is just a video game by a bunch of designers, and settle themselves back into playing.

I know I won't defend it too often in games, but what made Amnesia scary pretty often was realism. Making the experience feel somewhat real - like something that could actually happen to you - makes it all the more scary. Arms coming from curtains? Scripted sequences? They don't quite do it. I want it to seem like a monster was just wandering around as his stupid self, and happened to find me. Obvious teleportation and smartly sneaking up on me would just sort of ruin that experience.
