I enjoyed this vintage Mexican ghost story, it is entirely in Spanish (as it should be), and after watching it with apprehension, now understand how it holds its status as a cult classic.
The setting is a boarding school for girls, and one of them starts having strange dreams accompanied by sleepwalking, and panic attacks during the day. Claudia, the girl in question, tries talking to the school teacher but the principal is having none of it and keeps them all from going home during the winter holidays.
The situation escalates when another girl’s boyfriend breaks in to talk to her, and the source of Claudia’s sleepwalking is finally revealed to the school girls. The end of the movie is a bit of a twist on traditional ghost storylines, after a fashion. I liked how it ended. Worth a watch.
