I tried to listen to it FORWARDS just now, but it scared me too much. The feeling I got reminded me of when I was little (around 12), got freaked out by ReDeads in the Shadow Temple. And started seeing the eyes of skulls waiting to burst out of any set of objects I looked at that had two circles just the right distance apart, or imagining invisible zombies waiting to choke the life out of me if I passed by a certain location. The worst of them was when I kept hearing a voice that repeated the word "doom" over and over (unless I read something, and then the creepy voice would read whatever I was reading), proceeded by silence and and odd whistling in my ears.
Whenever things get so quiet that I can hear a strange kind of whistling in my ears (which only seems to happen when I get freaked out), I immediately look for someone to start a conversation with or turn on the TV. I'm too afraid that the next time it happens, I'm going to go completely insane and never make it back. I'm serious.
When I was even younger, I would occasionally be threatened by that voice with some kind of horrible punishment unless I took a particular action within a given timeframe. Interestingly enough, there was a voice in WoW that seems to say things very similar and of the same essence as the voice that freaked me out back then, only it goes to the extremes rather than starting small:
" They are coming for you...
Give in to your fear...
Kill them all... before they kill you...
They have turned against you... now, take your revenge...
Tell yourself again that these are not truly your friends...
There is no escape... not in this life... not in the next...
You are a pawn of forces unseen...
It WAS your fault... "
I don't know what exactly happened, but somehow when I was 14 or so, it got significantly better when I began looking at things from the perspective of this voice rather than seeing myself as the person to whom the things were being said. I became far more arrogant and less afraid... I suppose I merged it into my personality.
