The Grudge

i love to get creeped out and creeping my friends out. there is a video on youtube where the man goes in a house related to the story of the grudge..........the man was sent to spend a few hours at the house next to the house where the actual murders took place because a fire took the actual house and tht house had activity after. At the end of the video you hear something tht sounds like a girl or something and the camera guy turns to see something with three human heads before the camera abruptly shuts off...........two days after i was in the computer room when i heard this same noise. i ran out the house only to see tht no one was in the house at the time besides me....i don't think anyone believes me but i know what i heard.
