Rachel is haunted by grisly dreams after she becomes the only one who sees deadly images hidden in a series of grisly paintings at an art exhibit–except for the psychotic art major who did the paintings. (amazon.com)
This one actually sounds pretty good, aside from the overuse of the word grisly. It had me at psychotic art major.
