Histeria (2008)

Histeria is a horror film about six female students attending a supposedly haunted school. As part of a prank, they pretend to be hysterical and are so convincing that the school calls in a witch doctor to “cure” them. However, they soon find themselves faced with some truly mysterious occurrences and a series of grisly deaths that could either be caused by supernatural forces or by one of the girls themselves.

Unfortunately the movie Histeria is not yet available on HBO Max.
