I found something. Its looks like a small bedroom for 2 kids. There are a couple of toys and a TV. I'll update you guys once I figure out what the hell this is. Currently I haven't seen any entities but the lamp on the dresser seems to flicker on and off every 12 and a half seconds. I tried to look through the windows and open the blinds but they just won't budge. I got here after going through a door I found in Level -1, I chose it because it looked a bit off from the rest, it was more of a lighter black that the rest of the doors. The fan on the ceiling seems to work though. Like I said earlier, I'll update if anything happens, see you guys.
