Step inside... the House of Nightmares!
Sally's haunted attraction, House of Nightmares, opened in 2015 at Gröna Lund, the world renowned amusement park in Stockholm, Sweden. This terrifying attraction will bring visitors face-to-face with the evil Dr. Morphio in his old dark house where horrific nightmares await.
Specially designed for Gröna Lund, this one-of-a-kind walk through attraction features animatronic characters and props, CGI video effects, live wire illumination, video projection, Pepper’s Ghost illusions, ultraviolet illumination, and live performers.
The attraction is a complete redevelopment of a classic walk-thru haunted house...guaranteed to bring out your worst nightmares!
As visitors approach the exterior of an old Victorian mansion, special effects, lighting and sound help set the mood for the terrors that await inside. Scenic elements will enhance the back story of Dr. Morphio and his hideous experiments.
As they enter, visitors are immediately immersed in the story Dr. Morphio, an American scientist who specialized in the nature of human subconscious and the nature of dreams. It was in the late 1940’s, the formative years of television, when Dr. Morphio hosted a program entitled “DreamLand” during which he would interpret the dreams of guests on his show. However, at the height of his fame, his TV career came to a sudden halt when it was revealed that his personal research had become highly unethical and thoroughly illegal. The public was shocked to discover that he was conducting experiments on human subjects in which he attempted to forcibly extract their dreams from their minds and bring their nightmares to life.
Designed with an emphasis on animatronics and special effects, House of Nightmares is guaranteed to send chills down your spine.

Kings Island and Sally Dark Rides present Phantom Theater: Opening Nightmare
Maestro cordially invites you to step inside the Phantom Theater on a stormy night for the grand (and ghostly) opening of a long-awaited performance at Kings Island! No Legs Larry, the Phantom Theater’s legendary usher, needs YOU to help seat the audience. But beware…just before the show, a lightning strike has released supernatural ghost notes from Maestro’s famed pipe organ and they’ve run amok throughout the theater. The entire cast is calling on you to return them back to the organ before the curtain can rise!
Riding in enchanted opera boxes and armed with interactive spellbound flashlights, journey through haunted hallways, magical dressing rooms, and wild backstage chaos to capture the ghost notes before they ruin the show. Along the way, meet unforgettably familiar vaudeville stars, dodge a firing cannon, and witness operatic shrieks that shatter mirrors.
Will you save Maestro’s masterpiece in time for the show? Only one things certain: in the Phantom Theater, all the world’s a stage, and ghosts love a good encore! Phantom Theater: Opening Nightmare](https://i.ytimg.com/vi/_8P-JHSstcc/mqdefault.jpg)
