My heart feel so lost

I keep walking through these empty halls where the echoes tell me nothing at all.
Why does my heart feel so lost and small,
Like I've left my home behind the wall?
I'm reaching out, but there's no one there,
Just the cold wind and the empty air.
Tell me how to find my way back again.
Every light I see is just a ghost of what it used to be.
Every word I say is drowned by the sea.
