My father's place has a basement. It's entirely finished (except a small storage room, but that door is closed all the time), but it is pitch black at night. The computer was down there. I got to it by lighting pretty much every light on my way to it. When it was time to sleep and I had to close the lights behind me, I had to take a second to prepare, close the lights, and rush my way up there - always had that impression that there was a freaking ghost trying to catch and kill me.

I still do it when I'm there...
