It's a very complicated video and it’s very hard to understand it. This video is art, unlike the most of the music videos.
Most of the people think this video doesn't make sense, but that's only because they don't understand it... I can't explain quite good enough because the work of this masterpiece is beyond description.
You can see a blue text in the video on 9:56 when that guy is reading a letter, it blinks only for like 0.0001 sec so you need to pause it fast if you wanna catch it.
It says 'FIND THE ARGUS APOCRAPHEX', that means "Hidden Giant" in Latin. It can also mean "away from light".
That's the point of this video, you should face your fears and problems, your skeletons in the closet, which all of us have since birth.
That are the names of chapters in the video: 'Birth', 'Life', 'Death'. And that is what 'Argus Apocraphex' mean 'Hidden Giant' – your fears and problems.
Many people won't understand it because they haven't yet experienced weird and fucked up things in life.
