This is just a crazy idea but what if whenever you were surfing the web about lucid dreams or anything like that, play a song over and over until you get sick of it. Then when you try a WBTB play the song and all the information you got while playing that song will flood your mind.. The same works with smell. get a air freshining spray and spray it whenever you are reading about lucid dreams... then spray before you go to bed and you might bring all the ideas and information back.
