In a world where monsters really do exist, NBC's "Grimm" is stepping away from the fairy tales and digging deeper into the paranormal.
The spooky series aired a special Halloween episode where the usual creepy creatures get overshadowed by a haunting woman called La Llorona.
Its based on real-life folklore about a weeping woman who drowned her own children and then herself.
The "Grimm" cast and crew said the legend gave them goose bumps, but there was something during filming that scared them even more than the ghost story.
"I was in the Columbia River for a lot of it," said actor David Giuntoli, who plays Detective Nick Burkhardt in the show. "And they found a body, like 90 yards away from where we were shooting."
Giuntoli said the real Portland Police had to show up for that one.
The rest of their time on the Columbia River wasn't as frightening.
