The eye that had popped from the wall was the final straw; Lucas began losing his composure and could not think straight anymore. He stumbled on the floor, then slowly distanced himself from the terrifying sight. He shielded himself, waiting for the monstrosity to jump at him, but nothing would happen. The eye and the walls were morphing in front of him but, thanfully, weren't moving towards him.

A few moments passed before Lucas could move again. He didn't want to examine the eye anymore than he wanted to leave; fearing of whatever else may be waiting for him nearby. His hunger had gone from manageable to debilitating very quickly for some reason. He reached his pocket for the sandwich he found earlier and ate it quickly. 

While the rest of the facade indicated that he was trapped by some evil overseer who had kidnapped his child (and presumably the children of others), it didn't explain why he was seeing paranormal things. Realizing that the eye hadn't made physical contact with him, he brushed it off as a visual hallucination that would pass, and got up again. He shouldn't have been in this place after going down a second time. Either he overlooked something while going down the slide, or he was starting to lose it. He assumed the former.

The polaroid camera wasn't there before, and it was conveniently placed in front of the Morse code. This also looked like a setup. The architect of this place wanted him to pick up and the camera and use it. This also meant that there was someone else in the vicinity, following and watching him while carefully setting up each room. For a moment, Lucas wondered if he would catch the perpetrator by backtracking to the room with the pool, but he was too afraid of what he would find back there. The idea of getting jumped and thrown at the pool by the owner of this place made him hesitate.

He picked up the camera and snapped a photo at the Morse code. In a self-doubting move, he turned around and snapped a photo of the eye as well. If the eye was real, it would be imprinted on the paper. He then looked at the photos.
