Ahh, I remember one night...
Me and my bud were playing Silent Hill 3. It was near the end of the game, and we never got that far. Well, in one hallway, there is a normal door. Just a door. Right? You are DAMN WRONG. I went into this door, and was initially frightened by the room-sized mirror on the other side, but, whatever. I looked around in this tiny room and didn't find anything (note that the camera is always fixed on you and your "mirror-you", not to mention the whole room in the mirror) useful so I went to leave. The door was locked. Huh. Thats not supposed to happen.
Well, I look back, and the sink in the mirror's reflection starts bubbling up...something. Blackish-red. Gotta' be blood, I guess. Well, it's just the mirror's reflection doing that--untill the REAL sink starts doing it. By now, I'm thinking, "Wow, this is strange...". It starts to overflow, then, these...red tendrils start crawling up the walls at a slow, yet speedy pace. Note that it's only in the mirror. For about 1 minute. Then it starts to happen in YOUR room. Soon, the room is wrapped in red vine...things, and you start to notice something else. Your reflection...it's starting to get bloody! I'm running around with my katana out, waving it like a spazz, and the room turns black. Slowly, of course. It looks like millions of bugs are crawling all on the walls. Note your reflection is STILL getting bloodier and bloodier. I'm running around like nuts, I try to open the door again...still locked. Me and my friend are freakin' out, and as I'm running in a circle, there is one point where my back was facing the mirror, ready to make my 156478th panic around the room, and my reflection STOPS. It slowly turns to face you, and stands still, even if you move. Oh. Shit. Then, you die.
Yeah. Not going in there again. But I did. And I noticed that if you don't stay in there for longer than a minute, you can leave. Wierd, huh?
