Heres what you do:
Get a dream diary, keep it under your pillow and the second you wake up don't move, and focus on recollecting as much of your dreams as possible. After that, even if it's just the tiniest detail of the dream, write it down.
After a week or two of that you should have longer/more frequent lucid dreams. While in reality, ask yourself the question, "am i dreaming?" I know it sounds stupid, but it works, that way when you're dreaming you get used to asking yourself that, triggering the conscioussness within.
If you feel your dream is coming to an end, start spinning around in circles, it makes it last longer. I also found a strangely affective method of screaming, "lucidity now!" as if making your mind grant you lucidity. Eventually you will get better, but always search the web when you need more info. etc. on various sites, gather knowledge and collect it!
