Dreamcatcher is a great korean pop group that has some rock-like songs.
Their songs "Chase me" and "Good night" are specially good. They also have really good covers of "In the new world" and "Really really".
It's easy to suspect that the Dreamcatcher girls, though they are cute, are actually very evil.
In "Chase me" they are seen haunting a man in the same style as the movie "The Shining".
Further, the lyrics of "Good night" is all about how they are going into this mans dreams to give him nightmares and make him sweat in his dreams and they even say they will prevent him from waking up so he has to suffer through the entire nightmare.
They also dance in the woods and have a evil spell book. Thus; everything indicates that they really are very evil.
