I'm not big into horror movies. Haunted houses? No thanks. I'm a person who shrieks and gets startled by co-workers who sneak up on me (really they're just walking into a room or stopping to saying hi) about 500 times a day, so I don't need to actively seek out situations in which I'd be terrified.
Somehow though, there are some horror movies that I've accidentally watched. When I saw Buzfeed's 24 Perfectly Normal Things Horror Movies Have Ruined For All Of Us, it reminded me of all the irrational things I'm afraid of now because of horror movies.
