I will be working in a very low-lite room this year which will be pitch black for the Customers since they will not have time to adjust. The room itself is rather large probably 9x12 and I believe I will be working the space alone. I have a light prop for my face and a horn/light box at my disposal.

I have a head full of ideas swirling but I would love to hear anyone’s tricks or scare tactics for a room like this.

Thanks !!

EDIT. No trap Doors or drop windows. The escape from the room is a narrow walkway.
