>Story moments
>Mainly meant to help expand the universe and the story
>The main character is not payed to do what he does
>He works a crappy job, probably a bagger at a supermarket, lives in a crap apartment, drives a crap car, and might suffer depression. 
>He is also slowly going mad do to all of the ghost encounters (hallucinations, seeing ghost worlds without wanting to be there, ect)
>This would also be a time for the player to alter the corse of the story
>EXAMPLE
>You're driving your car over to the next ghost hunt
>You can pick up your phone, turn on the radio, look out the window
>SUDDENLY, A CAR SWERVES TOWARDS YOU
>If you're fast enough, you can get out of the way and keep going to your destination
>If you were distracted, you might hit the car and end up killing a kid in the car by accident
>A later mission would have you going to the crash sight and bringing the child to rest.

So yeah...I think there are some good situations for good spookyness

Examples
>Driving by someone's house on the way to a ghost hunt
>Suddenly, your vision blurs while you pass a house, your objective suddenly changes to "go into the house"
>Character: NO! FUCK, STAY ON TASK! *objective switches back and forth*
>If you stop the car, you go to the guys house, and make an excuse to come inside
>When you go inside, you find a psychic hotspot in the bathroom
>You use it
>Turns out that the man in the house is a serial killer, and there are a bunch of ghosts in his basement
