Have you ever approached sleep and dreaming in this way on your quest for lucidity?
I did this about a year ago, and it seemed to increase my dream recall by a ton.
Basically, I didn't think of sleep as "rest", I thought of it as something I needed to do in order to get as many dreams as possible.
So every night I would be like "okay, I'll just lie down for a while so I can get some dreams going" - then I kept doing that all night until morning, and sometimes I would be able to recall 5-6 detailed dreams in one single night!

It is all about changing your focus, so that instead of thinking of sleep as rest, you think of it as a "dream inducer".
I believe this can make your brain even more observant for upcoming dreams.
