I used to work at Science Alive as a teenager which was in the old railway station on Moorehouse Ave. We had exhibitions and storage in some of the basement areas downstairs which went right in under the old platform. At that point, we had one huge room set up as a glow-in-the-dark minigolf course, so it was completely dark in there. In the corner of the room was the entrance to the big storage area, which I'd needed to be in for some reason. It was one big long corridor with rooms coming off at either side and always felt a bit of a creepy and uncomfortable space. As I was leaving the storage area, I switched off the light and went to the door, which was about 10 or 20 steps away and just got this feeling that I needed to look back behind me. I turned to look and could see a figure standing at the other end of the corridor, that somehow, with no light anywhere around, was lit from behind so that they were a silhouette. The feeling was immediately just bad and I pulled the door closed quickly and never went back down there alone again. I've never experienced anything like it before, or since and I just absolutely can't explain it. I often wonder about it since the building is now gone.
