I can't even describe it, I looked at the lyrics without listening to the song and it really hit me. This I just my opinion, and it means something unique to each person so don't tell me that I'm wrong. I feel that it is about a person that is willing to give anything for "the fantasy", even their own life and their need for this "fantasy" has made them just a shell of what they were, not really living, just. I dunno. Being? If that makes sense
I actually am in love with this, the lyrics more than anything ♥.
