NOPE! I'm a chicken.
Although I think that @Shalott's fear is totally legit, I do want to point out that the story @allistra posted about actually came from a fake news site. Thankfully, for the sake of humanity.
My husband and I went to a haunted corn field last year. The actors were just local high school kids. The local university had a home football game that night, so we were literally the only two guests there. It was dark and out in the middle of nowhere. Since it was outside in a field, there were actual tripping hazards like ditches and rocks. The trail was fairly narrow in some areas, and most of it was poorly lit. There were also some long sections without any actors. It was intentionally pretty cheesy, but I got super spooked near the end. I realized (as we were being chased by zombies) that some crazy person could easily have snuck through the field, pretended to be part of the show, murdered me as I didn't run away, and ditched my body in the middle of the field. I won't be doing that again.
