Not spooky per se, but it scared the shit out of me:

I was 16 or 17 at the time and worked for a DJ pushing road cases and setting up/striking equipment. One winter weekend, upon striking everything after a wedding, I stepped outside around 2am to find myself in the middle of a blizzard. I had borrowed my dad's F250 with AWD for the evening, so in my infinite wisdom, I decided it would be fine to drive the 20 or so miles home.

There was absolutely nobody on the road, not even plows/salt trucks. Like many teenagers, though, I thought I was invincible, so I drove way faster than was reasonable in those conditions. About halfway back, I'm on an overpass across a major highway and hit a patch of ice. Cue the fishtail, then panic as my life flashed before my eyes. I ended up spinning about 2.25 revolutions, and come to stop perpendicular to the road with a few inches between my front bumper and the outer barrier of the overpass. Too bad I wasn't wearing brown pants.

I managed to get the rest of the way home without incident, but I have never taken any chances driving in suspect conditions again- I figure I used up all my luck surviving that event.
