Visions in the Dark

I am in a dark house with old dusty furniture. I am in the living room I think and I fall into a hole in the floor to the basement. It is dark beyond where the light from the level above comes through the hole but I can see rows of pillars or something. At the back there is something moving. I can hear it and barely see, but it is definately not human. It suddenly produces a small light source like a tiny pen light or something. I can see the light searching the walls and floors like it is looking for something. I get very scared and climb a thin water pipe back up into the living room. I am terrified of being found by anyone, especially by that thing in the basement.
