I'm afraid of getting eaten
I don't watch monster movies or movies with cannibalism in them because I am afraid of people being eaten. The thing that disgusts me most is being swallowed alive, which goes back to this cartoon I saw as a small child. It just seems like the worst possible way to die. I have no problem with watching animals eat their prey (even snakes, I'm more afraid of bugs), but I can't watch movies where people get eaten without feeling sick after. I get nightmares about this. I don't know anyone else who has this fear, and anyone I've told about this has said it's weird.
