Metal fan here. Not exactly sure how to interpret this video.
Initially I was loving it. Basically, humans have nightmares of monsters... but when you think about it, a monster would have far better reason to have nightmares about being a HUMAN! The alarm clock, getting dressed, the board meeting, etc.
Fuck that, better to be an ugly monster living the monster life than deal with that crap. I thought that was profound.
Then the bar scene started and it turned all mushy and my awesome interpretation got brushed aside.
UPDATE EDIT: I didn't realize the white guy was being a creeper in the beginning of the video. Now it makes a bit more sense.
