Only when I sleep stumble to the bathroom in the dark...Strangly the air turns blue to every time it happens....I think it's an Autumn thing as I only seem to do it in the Fall..... :)D
Yep, as I discovered one morning awakening upstairs after going to bed downstairs. Fortunately I didn't fall down the steep stairway, though it was apparent that I very nearly fell from the top straight over the open edge at the top to the bottom, as evidenced by everything that had been at the top ending up at the bottom.
