You asked for a file to help turn your favorite pillow into a physical key that would bring you nights of restful sleep. So follow me into my cotton candy clouds and let Daddy's whispers and echoes help craft a lasting lullaby to do just that.
Note: as the goal of this is to turn a favorite pillow to a physical key that placing your head on will trigger feelings/sensations, you need to actually lie down to listen to this file and USE said pillow while listening. :)
