Chattering voices whispering shouts until the noise becomes an incessant drone that can no longer be ignored. It starts to drown your thoughts and they too shriek in turn. Their cries rise and falter as they are absorbed by the waves of sound. You cannot hear the screams emanating from between your lips over the constant beat from a thousand drumming thoughts. Then it stops and all that breaks the silence so complete you cannot think is your racing heart followed by heavy breath.
