The weird five armed girl in the game Yume Nikki (ゆめにっき). Kinda... odd. This is how you get to her and also includes her and what happens when you use the stoplight in the room with her.
And yes when I go down in the dark place where you can use the lamp to make it easier to see, I make a circle. Not intentional; you do NOT have to do that. I just got a bit turned around and forgot which way to go for a minute.
