As far as i can think back i always had this weird thing that i heard something like distant voices whenever there was some monotonous background noise in the room (e.g. a fan running or so)... sometimes i could swear that someone called me from downstairs or from the neighbouring room, but in 99% of the cases nobody was there. Though... never spoke with a doctor about this, i just accepted it as one more fact on the "i am sometimes weird" list.
