Like you said, the initials could be from an earlier point in development, which is maybe the case here. However, you said that the statue thing could be a dream, which is plausible, but I don’t believe it’s from a different game. For reference, I had the experience around the same time when I was still terrified of playing FNaF 2, and I was (probably) 10 so it couldn’t have been from any horror game since, you know, I was really scared of horror at the time (I still kinda am now but that’s besides the point). Maybe if we looked into the mobile files of the original Room because that’s the only version I have then we can see if the picture is still there. I’ve never seen anyone else talk about these games’ unused content online, so this could be incredible if we did find out anything
