If you want a game: Outlast, next to Amnesia the game that scared me the most.
If you want a movie, depending on which scares you more: Demons (First "Paranormal Activity", "Emily Rose"), Ghosts ("Shutter"), the Unknown ("Sinister")
Easy get scared recipe: Any of the above while being alone in a room with lights off.
If you're getting into Pathfinder the rulebook apps are pretty good and super easy to reference in the middle of a game.
I started playing DnD for the first time by walking into a local gamestore while they were about to start a weekly and asking to join. We've been playing together for 3 years now. I'm pretty sure I just got lucky though. ^^ ;
