I really like this, not only the voice really fits nightmare, but the song really fits him, the emotion in the singing was amazing, and the singing was amazing by itself, well done! I really got the feels from this.
this is soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo cool
I've always resonalted with this song, but I think it represents Nightmares struggles more symbolically. He's always scared somewhere within himself... and the cycle continues, ever eating at him... it's.. rather tragic actually.
