The only time I can recall myself having dreams are usually a few minutes before I wake for some odd reason, and the rare times I do dream I have full control over them and that's alright i guess even though I always end up dead or about to die… I personally have never heard of lucid dreaming so i dont have much to say on it sorry.
Keep a diary beside your bed. Write down the few you do get the instant you wake up. Read them before going to bed.
If you sleep very deeply try setting a clock to wake you up a couple of hours before you need to get up. Then when it wakes you up, fall asleep again. Experiment with the timing of the clock.
If your life is too boring it shouldn't be impossible to reserve long times for sleeping. That way you can wake up every 2 hours to record your dreams.
My experience is that if you wake up and go back to sleep you can dream more. I guess during long sleeps you forget the dreams you see in the beginning, or something. At least some parts are hard to remember.
