Minor Spoiler..

If you go and look on youtube for the soundtracks (1-25) the titles kinda give you a clue as to what is going on, and better yet if you listen , you can sorta picture what might be going on... (Eg. one title is called "Old Friend", and sounds almost exactly like its from Alien.) But then again, it's just the music/sounds. some gave me goose bumps like none other just thinkong what might be going on..
