I listened to the "Sleep Instrumental". I must say that it is one of the best piece of music I've listened to in a while. It might sound funny but what came to my mind when I listened to it, is a man who goes to sleep as you say, but in a hospital with green tiles on the walls, rusty coloured bedposts, misty green sheets and huge windows that view the world in black and white. The man goes to sleep in this room, leaving his dreaming ability aside. He just sleeps on the bed but as the music continues the world he rejected begins to appear in my mind. His parents fight with each other near his bed, some war scenes appear in view from the windows, bombs begin to break down the walls but still the man continues his sleep. As the music's frequency increases towards the end, man in white uniforms appear, alarms begin to roar and shout to wake him up but he is so determined to sleep that nothing can wake him up. Also I sensed some Marilyn Manson type of notes in the music which makes listening to this song even more enjoyable. Great work.
PS: I have been writing horror fiction for sometime now, and I must say that this music is inspirational for me.
