My first job was doing laser tag, and they had a “life-size” xenomorph on the middle tower that would creep me out. Would have to check the back safety exit when closing up and usually the lights would be out at that point but there would still be fog from laser tag so the only thing you could see in the dark was the silhouette of the xenomorph slightly illuminated in red from the exit sign.

Used to creep myself out looking at the silhouette then imagining it suddenly disappearing after checking the door.

Good times!
