Well I don't have this problem myself, but I heard that instead of writing about what you "see" when you wake up, you need to write about what you feel.

I do this when I know I can't remember part of a dream, but have a feeling about it. E.g - the other night I kept seeing people clamber over things and got a very peculiar feeling about it, but I didn't feel like i'd dreamt about it. So I wrote the feeling down.

This pretty much brings attention to the fact you want to dream, so you begin to. Luckily I dream every night, without fail I guess it's because I've always loved and been interested in dreaming, even before I knew about the lucid aspect of it
