Dust in Your Head

I know that the cloud of dust in your head Seems like a permanent, unloyal friend But outside the glass I swear to you now There's a wide open gap Beyond the white sound So hold on to that ladder step And don't let go I know that the film of simmering dread Can be unforgiving Like the mercury said You can hear the floor begging Return to the ground Let go of the ladder And drown out the sound
