I've seen some movies that have made me hide more under my blanket at nights, but never gone completely out of my mind
I tell myself not to have any bad dreams about the bad things I have in mind, and I end up with these weird dreams where we're for instance beating the girl from the Ring (she didn't even look scary) with baseball bats, wearing underwear around our hands because it was her weakness, and we totally kicked her ass
I'm also quite a good orc slayer! And the guys from Funny Games aren't really that hard to beat in a pillow fight.
Just saying some fear doesn't always give bad twists, but of course it might.
