So, I'm living alone for a while, and I have a very old Victorian house. It is full of twists and turns, and sometimes I psych myself out by imagining something popping out from behind the corner, and it's becoming more frequent. Sometimes, when I'm going down stairs and take the corner, I have to whip out my phone and shine light around the corner before I go. This also happens with the sliding shower door and the doors in the bathroom. Is it normal?
