:?: In my dream journal, besides writing down the obvious, I also write down the day and what position I was lying in when I had a lucid dream. Although there was only a slight preferance towards dreaming on Sundays - I noticed after going over my notes that it was a clear advantage for me if I were lying on my back, to have a lucid dream. Who else is aware of what position they were in at the time of their lucid dreaming?
