Whats the name of that horror movie that just came out that everyone is afraid of?

I dont know the name or what its about, but iv seen 2 newsletters on it saying that people have not been able to sleep at night and that even a reporter had to watch it to make a report on it and she couldnt sleep either. They also said that the movie wasnt approved in some states because it was way too scary?? It just came out a couple of days ago! Does anyone knoe the name and what its about? Why so scary??
