Save behind the walls

I've created a place
A save, hidden place in darkness
It's surrounded by walls
As high as the clouds above

I've created a place
A shelter, to hide from the world
Only one key that I hold
And I close the door behind me

So save, but so alone
Lost in this world, lost inside myself

Do you see the walls?
Can't you hear me knocking, knocking
The stone too thick
The sounds are fading
Knocking, knocking
Are you there?

Bring these walls down
They're so save around me
But I can't bare the emptiness anymore
I'm so cold, I'm so lonely
Save me from this place
