Congratulations on your increasing lucidity. I haven' t been around the board lately but my efforts to be lucid has never stopped.

I think persistence is the greatest factor in achieving lucidity. I also find that I have a much higher chance to achieve lucidity when I get a feeling of my previous dream before going to bed.

It's actually quite a strange feeling and my ability to put my self in that state varies greatly. Some days it comes very easily and some days I just can't seem to recall them. I've noticed that the more tired I get, the more I can recall them though and this may tie in to what you've been experiencing.

Good luck
