a scary thing: playing Fatal Frame 2 at midnight in complete darkness with surround sound
a scary situation: seeing spirits it's happened twice now, and im not sure if they even were spirits, but the experience is hard to describe.. one of them looked like a regular person, but strangely, i seemed to be seeing it with my mind, rather than my eyes.. the other one looked like a lightsource of some sort.. both were brief, and like i said, im not sure if they even were spirits, but it was freaky to hear that nobody but me saw them)
a scary scenario: knowing that you're gonna get murdered within 12 hours, but not knowing when or how it will happen... sounds scary enough to me
