DEMONS.

Imagine Dragons - Demons

...
They say it's what you make
I say it's up to fate
It's woven in my soul
I need to let you go

Your eyes, they shine so bright
I wanna save that light
I can't escape this now
Unless you show me how

When you feel my heat
Look into my eyes
It’s where my demons hide
It’s where my demons hide
Don’t get too close
It’s dark inside
It’s where my demons hide
It’s where my demons hide
