My kid is freaked out by shadows. I have that problem, too. Bad vision does something to moonlight when you take off your glasses. Knowing I'm a wuss I don't watch horror movies. My imagination supplies way too much backstory and all kinds of probable scenarios.
I was working last night--sitting near my window (it's 75 degrees here! My God it's hot!) sometime around 11.45 pm. It's dark, and the entire town rolls up the sidewalks at eight. Streetlights get fewer as you get away from the downtown core. The last time I had to walk somewhere, I was totally in the dark and I mean that literally. I only knew there was a sidewalk because I'd walked it before.
So this noise starts up....
...scree rattle squeal scre scree screee. Rumble. Over and over, rolling down the invisible sidewalk at 11.45 in total darkness. Scree scree rumble.
...and my brain supplies "red rum. red rum. scree!! RED RUM!" and I'm just about falling off my seat, no one else notices. The noise gets louder and louder, until it's right under my window, then it fades away.
Like the mom in Pet Cemetery who can't open the door, "knowing" something that looks like her son is on the other side. I don't need movies, I have books. But I really wish I hadn't read The Monkey's Paw.
