Amnesia: The Dark Descent. Not scary anymore :(

I've been playing Amnesia The Dark Descent for some 400 hours total. I've mastered the game 9 times. Each ending in all 4 ways.
-Vengeance
-Rescue Agrippa
-Shadow consumed (Cells)
-Shadow consumed (Inner sanctum)

The game on average took me from 16 hours to a day. Now it only takes me 4 hours. I know every tinderbox location, every puzzle, all eastereggs. I read the wiki about all 27 levels already, I know where each jumpscare and each servant grunt, servant brute, or Kaernk spawns. I've also installed 2 custom stories that I've already beaten. The game just isn't scary anymore, where it turns into an everyday thing. 4 hours from the Rainy Hall to the Orb Chamber. Amnesia is getting very dull and boring. Anyone know how I can make the game seem scarier, or in other words "forget" what happens in every square foot of the game? I mainly play on the Madness Ch03 demo now, where the monster is yelling very nasty things at you. And he's fast and strong and so as a forth.
But anyway. Someone help me! Amnesia is BORING now.

 

I remember playing that game... My mate was watching me and he said to play that game for half an hour. I told him I would shoot for an hour. Half and hour passed and I did not come across 1 scare... I closed the game after 45 mins because it got a bit boring. He said that I managed to miss all the bloody monsters some how. I didn't believe him so I played it again, first 1o mins and almost shat myself. Screw that game, to scary.

 

My profile picture is a servant grunt. These guys are my favorite. Something about their growls and hisses makes me feel nostalgia lol. They're cool and fun to troll. Slow, Ugly and stupid. That's how they are. :)

 

Yeah... that's the thing that made me close my game. xD

 

I've renamed all of them :D
Servant Grunt - Steve

Servant Brute - Gregory

 

Meh, It's just some guys with terrible last spring clothes and wide open mouths. It's normal. They also taste like my uncle

 

I've read the story behind Amnesia. Servant grunts are the weaker and slower type of grunt. They serve Alexander only. Servant grunts were Wilhelm's men that drank bad wine and malformed themselves, giving them rugged skin and a long stretched jaw, making them unable to speak. They can only make a variety to growls and hisses. If you listen closely to the grunt's noises, it sounds like an attempt for normal speech. Sometimes grunts can be heard crying when calm (Sedentary, not searching or attacking). Servant brutes are the rarer more powerful types of brutes. Before this story took place, Wilhilm's face was split in two, skin boiled and limbs ripped apart. In the picture it appears as someone pieced their corpse back together (Alexander?). These things match the brute.
