The sleep is the moment when the subconscious gets the upper hand and can make us live our biggest fears ans our biggest desires. It repeats this melody since the bottom of our spirit until the madness.

We have to be afraid of this part of us, we have to be afraid of its kingdom that is the sleep, Narkophobia, this is what it means.

(sorry if there's some mistakes, correct me if necessary =) )

This track is one of my favorites
