Even though the school footsteps don't really bother me much, I'm a bit of a wimp. Okay more than a bit. I read King's The Shining in high school and haven't read a horror book since! He scared the bejeepers out of me. I had nightmares for months (okay...years). To me the characters were so vivid - and he made the situation real. I believed. So I was terrified.
I heard years later that King himself is a bit of a 'fraidy cat. I don't recall the details, and I don't even know if it's true, but I read that King checks under his bed and in his closet every night before he goes to sleep. Hmmm.
So, does it help to be easily frightened if you want to add some horror or spooky elements to your writing? Are the brave souls not the ones who write the best horror? Does it take those of us who imagine the worst horrors to write the truly terrifying stuff? What do you think?
