One night within our first year or so in the new house, I awoke on the floor not knowing where I was. I crept in the dark to the nearest window, and looking out I realized that I was on the third floor of our house, in one of the tenant bedrooms. As quitely as I could, I made my way back to my bedroom on the floor below. My first theory was that a burglar had come in the night and carried me upstairs, but the next morning I was soon convinced that I had been sleepwalking.
