The Spell Knows My Name

I said goodbye, the silence said no.
A second pulse beneath the sound.
I tried to leave, it pulled me down.
No touch.
No trace.
Still every silence takes your shape.
The spell knows my name.
It calls me in your voice.
The spell knows my name.
I never had a choice.
I swallow the sound, it moves underneath.
The spell knows my name.
It sounds just like me.
If this is gone, why does it move when no one breathes?
If this is love, why does it wake when I try to sleep?
