This kind of thing was happening to me when I first got interested in lucid dreaming - the best advice I got was this - make sure you write in the journal every morning, even if you cant remember 99% of it, remember any details and you can, and make the rest up.

Making it up sparks your imagination and stores it as false memory anyway - Nobody is going to check the journal and make sure you are doing it right, its simply a havbit to increase dream recall!

The other thing is to stay positive, If you say to yourself that you cannot achieve lucidity, you wont.

Accept the fact that you are dreaming a lot more than you think, its simply your recall that needs to be improved, which will, in turn, increase your chances of lucidity!
