Last Tuesday night around 11pm I was driving home on highway 17 near Santa Cruz. Kept hearing this clicking noise from the backseat and seeing movement in my rearview mirror. Freaked me out so bad I almost pulled over on the shoulder. Turned out the passenger side belt buckle was dangling and hitting the plastic trim every time I hit a bump. The reflection from passing headlights made the shadow look like a hand reaching up. Now I always buckle every strap before I drive, even empty seats. But honestly I'm still a little jumpy at night on that stretch of road. Has anyone else thought their car was haunted but it turned out to be something dumb like a loose cup holder?
