I spent the last three hours reading ghost, UFO, and general "unexplained mystery/death/disappearance/etc" stories and listening to Numbers Station recordings.
You'd think it'd be harder to actually get creeped out by such mundane things taken individually. I think I'll lay the main blame solely on the shoulders of the Numbers Stations, though. The audio quality and recording hiss and noises, and creepy monotony of the voices and nonsensical lines that could mean anything, broadcast over and over endlessly all over the worlds in different languages and codes for over half a century...
It's eerie.
As I was walking down the stair,
I met a man who wasn't there.
He wasn't there again today.
I wish, I wish he'd go away.
