Halloween // Need help with haunted house concept

Gang, each Halloween we decorate our three car garage into an interact haunt experience. Last year we did 6 separate hallway experiences and incorporated pneumatics.

This year, I want to created an actual haunted house experience at the 8-16 age group. Yes, it's a scare experience that boarders more onto the actual adult scare side and not a kids experience.

I really need ideas to use for each room experience using sounds, jump scares and pneumatics (air powered) for the following rooms as well as the underlying story to drive the experience.

Living room Kitchen Bathroom Bedroom

I have hit a wall on the story and the scares so, I greatly appreciate your fresh view.

Thanks in advance
