they started out sounding through fans and fridges, air vents. it seemed like a voice to skull attack from the start.
then one day they were as loud as jet engines sounding from the walls, and outside from the sky.
at first it was calm voices telling me to obey them. then it turned into evil beings touching me trying to kill me, i had a seizure once from that
all along i knew it was a technology but took me some tries to affect it
