I noticed this alot as well when I first started to develop my own dream recall. At first there was not much success in remembering anything, but soon enough, using a range of simple techniques I slowly improved (and still am).
Although I haven't experienced lucid dream yet myself (or, at least, haven't remembered any) I can list a few things that I've learnt:
In your waking life try to remember everything in order that you did throughout the day, as accurately as possible. By improving your memory you therefore benifit from a better dream recall.
Do reality checks whenever you can within waking hours. Such as, looking at the palms of your hands for a few moments, reading text, looking away, and reading the same text again, because within your dreamworld such things as text and clocks aren't very consistant and usually appear distorted or unreadable if focused on for long periods of time/ looked at ever so often. Through habit, naturally, you will do the same checks within your dreams as well.
Simply asking yourself something along the lines of "Am I dreaming?" constantly throughout the day will also increase your chances of attaining lucidity while dreaming. Like before, this will create a habit that will carry over when you're alseep (at least that is the idea).
Much like the one above, just by placing notes around your house asking the question "Are you dreaming?" will reinforce the thought pattern of being aware of your current surroundings. This is the most recent one I have applied in my efforts to gain a complete lucid state within my dreams.
And while you're at it, practice visualisation meditation to get a better grasp on remembering certain aspects of a dream and gain better clarity, which could help in some ways to improve your dream recall.
And of course, keep writing! regardless of how vague your memory might be of a dream (or what you think the dream might have been).
Abundant memories to you!
And if you achieve a lucid dream before me, congratulations to you all the same.
