In a lot of ways, it's easy to brush off a scary picture or video we see on the internet. At least, that's the impression I get whenever someone posts one because you can always expect a bunch of people to immediately let the world know how not scared they are.
Of course, that confident feeling can quickly change when you're no longer separated from the scary thing by a screen and it's unfolding right in front of you. And no matter how tough we are, it can feel realistic enough on some chilly nights that it's easy to forget the screen is even there.
And whether it's due to our imagination filling some unpleasant blanks or a sudden reminder of a frightening memory, it's suddenly much easier to remember why we wanted a night light as kids.
