They say there's some kind of monster But I don't think that it's under the bed You keep holding on You think I'm some kind of freak But I remember we used to laugh every time You once said these monsters will sleep in your heart I will never be on my own It's haunting me because I'm alone Through the door is another you But it's the devil It's the devil Devil Inside you The devil Devil Inside you Sometimes it takes us so far from home But does it happen the same way twice Oh you're holding on And if it means you destroy yourself Well you won't need to run any more You just need to always believe in you Always believe in you I will never be on my own It's haunting me because I'm alone Through the door is another you But it's the devil It's the devil Devil Inside you The devil Devil Inside you The one The one The one How dark could this empty room get? I'm prepared to fight You will always feel it somewhere Feel the fire I can be the one I will never be on my own It's haunting me because I'm alone Through the door is another you But it's the devil It's the devil Devil Inside you The devil Devil Inside you But I But I can be the one
