Scariest moment in an exorcism movie ever IMO
The part where she is in the barn and finally says the names of the demons and finishes with "And I am Lucifer, the devil in the flesh" and her face is shrouded in darkness is so damn scary it still gives me major goosebumps.
Just to follow up with a little humor I love how RIGHT after she says that they show the horse and his eyes/face are like "Fuuuuuuuuuq that I am out of here!!" and he kicks the door away and get's out LOL!
