Okay, maybe not a clown. But the grudge will.
I was mucking about on my friend's ipod touch today and I clicked on this one called 'Haunted'. You saw this empty house, furniture moves a bit and then BANG, the grudge jumps out at you.
I screamed and flung it away (Okay, I threw it a few centimetres onto the sofa next to me, what whatever) and prompty burst into tears (I suck so bad). My friend immediately apolgised and explained that she had it on there to scare my other friend, but she hadn't mean't for me to see it (since she knew I'd be freaked out by it).
My other friend then watched it and screamed, dropped the ipod and fell off the sofa. Just wanted to let you know.
So anyway, yeah. Its nearly 2am, but I can't sleep because otherwise I will
A) See things in the dark
B) Have nightmares.
Oh well, at least its the holidays

EDIT: I can hear my brother snoring through the wall. I keep thinking that it is the grudge making noises. Damn it!
I find the best way to beat fear is with a cunning technique. Imagine the grudge appears in your room at night. What will you do?
I like to think of epic ways I can go out in a bang. Say for example, I might yell out candy and tackle her/him. Beats the old horror film cliche. How many people have been killed by a monster because they bear hugged it?
