The Slapping Ghost

Informant: Male/22/Hawaiian - Portuguese ancestry
Location: Lihue Airport, Kauai

I was sitting across the street in the smoking area one night waiting for my ride to pick me up. I was just minding my own business smoking by myself, nobody was around at all (it was pretty late at night). Suddenly I felt something gently touch the back of my neck. I ignored it; I didn't turn around to look if anyone was there.

Maybe I should have, because two seconds later someone slapped me hard on the back of the head. I jumped up and ran across the street. I still didn't look behind me.
