High Octane Nightmare Fuel – "… A Psychopath" is sung (in a disconcertingly child-like voice) from the perspective of a woman being stalked, who lies in her bed with a baseball bat and can of mace, paralysed in terror. If this wasn't enough to put it in Nightmare Fuel territory, there's a recording of a real 911 call playing in the background, featuring a horrified woman with an intruder in her house.
Someone commenting on the video above noted that, at the 2:10 mark, it sounds like the woman says "Bundy," making the song that much creepier...
