I have had (terrible) times in my life when I felt fearful of a piece of furniture. It is so illogical and SO frustrating! But it happens. I had a very severe breakdown this past winter and one of the horrible "things" about the breakdown was that I developed a fear of my bed. Totally crazy. Nothing bad had happened in my bed. My bed just sits there. I still slept in it (strangely, I was okay once I was lying down), but whenever I pictured my bed in my mind I felt fearful. Getting the right medication regime going has helped immensely. I really believe that in most cases, these kinds of fears are just brain chemistry gone haywire.
