I have heard of this before. Apparently, a boy died in the house that the movie was filmed in just a week or two prior to the filming. There is one scene where a boy can be seen behind a curtain in the house. I did a little bit of searching on the internet and found out that this ghost was actually just a mis-placed cardboard cut out of someone else. Whether or not that is the truth, I do not know. But the story has interested me to no end. go here:
http://www.jkcinema.com/ and click on 'urban legend series' (NOT urban legend series: ufos, the one below that that just says urban legend series) and one of those videos should have the scene from the movie in it. All of those flash movies are very interesting thouhgh, and I would recommend watching all of them.
