A flatline in the mirror

The beep beep beep, in this silent room, is like the boom boom of my heart, sound of the base,
out in this people maze, dancing moving, now feel better.
But if you turn around listen to the sound, all you hear's a funerals marching band.
We had another drink, feel your defenses sink, call for the medic but he isn't there

Somone who you held dear, who saw you nowhere, is slowly falling sinking down to the knees.
So take another bow, cause it's over now - only the Flatline awaits.
