The house, which is more than 100 years old, has actual documentation of ghosts, said owner Mike McCormick.
The front window is a common place for paranormal activity, McCormick said.
"Every psychic who has stopped here-and there have been several-have all described the same old man looking out at us from the window," he said.
Omaha's WOWT Channel 6 brought in a psychic in 2000, and Prism Paranormal investigated the house and captured several electronic voice phenomena, known to ghost experts as EVPs, he said. The footage is online here.
"We leave the haunted thing up to you," McCormick said. "If you feel it's haunted, then it's haunted."
McCormick and crew don't believe in blood and gore. It's doesn't require any thought or creativity, McCormick said. The crew really plays off of their theatrical ability to scare.
McCormick tries to add or change something every year. This year, it's Heartbeat Bridge-a rickety bridge, counterpart to the Hatchet House urban legend.
The legend has it that in a one-room schoolhouse, known as Hatchet House, a teacher chopped off the heads of all her students and threw them off a bridge.
"We like to think of urban legends in the area," McCormick said.
Haunted Hollow is not just a haunted house, McCormick said. There is a barn maze, funnel cakes, a public bonfire, Halloween shops and many other attractions. The owners even make their own scary labels for pop.
Haunted Hollow is open from 7 to 10 p.m. Sunday through Thursday, and 7 p.m. to midnight on Fridays and Saturdays.
Admission is $13 with a $1 discount for every customer who brings in a non-perishable food item Sunday through Thursday.
"There's a lot to do for one admission," McCormick said.
Haunted Hollow, a family business, started in 1999 and is going on its ninth season.
