It sounds slightly off key which makes it kind of like gently rolling into a nightmare. Abnormal. Pretty cool.
Thank you. One of the sounds I used was a cathedral bell type of thing; They resonate slightly off key. Of course, I threw in a couple of dissonant notes myself, around the 0:37 mark. I can't say that I specifically had your interpretation in mind when I created this song, but "gently rolling into a nightmare" sounds pretty awesome. That's one of the things I love about art; Once it leaves your head, it takes on a life of it's own.
