A fresh trailer for a new Insidious sequel has arrived — and it’s already sparking a jumpy reaction online.

According to a new report, horror fans are warning the footage is so terrifying they expect to be “having nightmares for weeks”. The update also suggests that even seeing the trailer during the pre-film adverts at the cinema could be a shock, with some viewers potentially wanting to bolt for the exit if they catch it on the big screen.

The update describes the franchise as a cult horror and says it’s getting a brand new outing in sequel form, with the newly released trailer fuelling the fear factor before the film’s release.

For fans who love the Insidious vibe, the trailer drop looks like it’s doing its job: building hype — and dread — in equal measure.
