Slasher films are a lot of fun to watch. But what exactly would it feel like to get stuck in one?

Scientists have explored many of the things that happen to the body and the mind as it approaches death — and while much of it still remains mysterious, the experience can be understood through the various chemical reactions and events that are happening in the brain.

Just in time for Halloween, a new video from the American Chemical Society explores exactly what would be happening inside someone's body as they are being chased by a murderer in a slasher film.

The creators of the video point out that the experience of watching people get chased through a slasher film is actually similar to being there — though the actual thing is presumably a little more intense. The same sense of adrenaline and fear is activated in the same way in both cases.
