I wonder if anyone else has experienced this... and if so what did you do about it?

I started trying to lucid dream and remember my dreams about 3 weeks ago. I started keeping a dream journal and my dream recall immediately improved to the point where I was remembering at least one dream a night and they were starting to get longer. This is up from usually remembering nothing about my dreams so I was pleased.

My wife and I moved our bed to another room (same house, same bed, not a massive change) about a week ago and suddenly my dream recall plummeted to zero. Now, despite still keeping a pen, notebook and small light by my bed, if I'm lucky I only remember fragments of a dream. What happened? If I can't remember my dreams I can't lucid dream so this is a major setback. Any thoughts?
