Just so everyone knows this is the girl from The Grudge and this idea is a
bit graphic so it is recommended for older peeps.
Get a white dress and find a way to wrap it in clear plastic that is stained
with blood.
Dye your hair black and straighten it but don't put any gel in or
else it won't blow around.
Put white face paint on your face (don't forget to
cover your lips also), arms, and legs (the legs aren't necessary) Take a light
color of red or brown face paint and have someone smear it on their hands and
then grab your neck from behind (this will give the effect of how she died).
Pile on the eyeliner and make croaking or groaning sounds and you are
guaranteed to get a few screams.
Thanks to LuvHalo for this creepy idea!
