This October, your imagination will be severely tested as The House of Frankenstein’s notorious horror event After Dark presents ‘Parasomnia’ – a twisted journey through waking terror where the lines between reality and nightmares are erased.

After Dark – nights to die for returns to the House of Frankenstein from 18 October. Those who dare to enter will experience the psychological paranoia of total darkness, confinement and an assault on all the senses as they venture over five floors of torment, whilst encountering hellish characters that tap into our most deep-seated fears… 

After Dark – nights to die for challenges visitors to:  

• Conquer 10 chambers in a 300-year-old house in total darkness.
• Navigate dream-state labyrinths, dead ends and confined spaces.
• Endure physical manifestations from the darkest corners of your subconscious.
• Venture into the foreboding underbelly of the building.
• Devour curious mind-bending shots in the bizarre Carnival Bar.

After Dark will run at Mary Shelley’s House of Frankenstein from 6pm -10.30pm (last admission 9.45pm) between 18 October – 1 November 2025 on selected dates. Evening Escape Rooms, which include entry to After Dark horror nights, are also available.
