Strange Events on Modern Horror Movie Sets

Doesn't a movie about a haunted house, where a child is rendered comatose and essentially possessed by some rather malevolent spirits, sound absolutely fantastic?

It has been reported by the actors involved in the production of this specific horror film that they frequently experienced feelings of sickness, heaviness, and overall unease while on set.

Furthermore, an incessant buzzing sound could be heard emanating from one of the rooms, even though it was unoccupied.
