You know the whole "Writing down your goals" thing? Well I don't use that for alot of things, but a few weeks ago, I thought instead of just repeating "I will have a Lucid Dream and I will remember it" I'd write it down.
I wrote an email to Dr. Neil Slade, he's an expert on the human brain and the frontal lobes and brain self-control.
I asked him if you were to write something down, like a goal, would it set your mind to do it. And he said yes it would.
So I tried it, my results were VERY good, I had 1 big LD and 2 small ones in a week and 2 days.
So instead of just repeating the phrase in your head, write it on a peice of paper "I will have a Lucid Dream and I will remember it"
Even if it dosn't work the first time, do it every night, your brain will start picking it up more and more and start recognizing it and remembering it. Try other things as well "I will wake up after every dream period" "I will completly recall my dream", things like that.
Try it for a couple of weeks and tell me your results, and then keep doing it.
