When I was living in Finland on an exchange trip I was in the darkroom processing film when one of our guys, Brownie, asked the other three of us to switch the redlights off while he did some developing. We dutifully waited - and waited - and waited. Unbeknown to us Brownie had left the room as a joke - leaving us waiting interminably. When Brownie did turn up again switching the lights on and laughing we all groaned - except for Karen. She was adamant there were four people in the room the whole time. Brownie was adamant he left the minute the light had gone off - very strange. Later on Karen confided in me she had I-see-dead-people syndrome, since she was a kid. She'd seen ghosts and disembodied heads above her bed at home. She made me promise not to tell the others. Thus we were wondering who the extra person was so I devised a plan. I would sit with Karen in the darkroom, switch the lights off and WAIT. Simple enough an idea, and pretty silly, but I had no idea to expect what did come about. We sat in the room and Karen was talking to me the whole time, and we werent taking it seriously. It was pitch black, the only noise being the drip of some taps and a few winking lights on the machines. Then her voice started wavering in the dark, her hand went for mine and I started getting a bit worried. Then mid sentence she started SCREAMING, which totally blew me, screaming as much as a person can scream. I was so terrified I shut my eyes, I didnt want to see anything. So there we were, one girl screaming and me standing there wetting myself. It just went on and on. In the end I took her hand and walked her across the room. I could either have gone for the door, but it was a revolving one which took some time to revolve (an extra safety measure for the darkroom). I decided on the light switch, holding her hand and her screaming the whole time. She was frantic. I pressed the switch, and get this, it wasnt working. I think that was the one scariest moment, realising something really was wrong. I tried again and again and again flipping it but nothing worked. In the end I walked her across the room again (still screaming), completely black and we went into the revolving door and SO SLOW it was, but we were out again. I cant describe how scary it is being in a utterly pitch room with someone screaming in your ear for a few minutes. Later, after she'd calmed down I asked her what the hell happened. She said she saw two figures, one large and one small. It was only when the small one came up to her and stood at her feet did she start getting really scared. Then it opened its arms as if to hug her and thats when the sreaming started (she shut her eyes then). The college was built on reclaimed land from the lake in the 1990s and was thus very newly built. Later we found out the Institute was founded by an old lady and her grandson, a boy at the time. I dont know to this day what happened, all I can say was there was a lot of darkness, screaming and light switches that didnt work, but worked fine after.
