Today, I had two separate moments when I got scared, both due to the effects of stereo. The first was this morning, when I was driving my wife to work. We were listening to music, when on the far right side of the car, came a spooky "oooooh" sound. It startled me, and I thought my wife had seen something on the road and was "oooh"ing me to avoid it. Turns out it was Emmylou Harris singing backup harmony on a Ryan Adams song.
The second time was at lunch. I was walking back to work, with my headphones on, when deep in the back of the sound came a strange sound, which I interpreted as footsteps of someone behind me. I knew there was nobody behind me, so the thought that all of a sudden someone was behind me was a bit unnerving for about half a second.
Damn you Stereo and your two-channel spookings!
