The Twilight series has always provoked intense physical feelings among its fans: heart rates suddenly speeding up every time Taylor Lautner takes off a piece of clothing, hoarse throats from all the screaming at Edward Pattinson, and jaw pain from all the grinning fans do whenever Bella and Edward are on-screen together.

But seizures? According to ABC News, “Several instances of people saying they have developed seizures during the tense birthing scene in Breaking Dawn: Part One have been reported. The in-theater seizures, also known as photosensitive epilepsy, are thought to be a result of the bright flashing of red, black and white during the film’s nerve-wracking scene.”

We remember hearing tales of people getting nauseous during classic horror movies of the past — Exorcist barf bags were infamously given out, and fainting was common for Psycho’s movie theater audience — but we never thought Breaking Dawn: Part One, or any Twilight movie for that matter, would reach fright night levels of horror.

So beware: along with all that heart flips expected when watching the newest movie, keep your eyes closed during that scary childbirth scene if you don’t want to freak out too hard.
