This is all just a theory, but I think the lucid dreaming method OCILD (Owl City Induced Lucid Dreaming)(which I just invented) could work in the same way DILD sort of does.

HOW TO DO IT: listen to the song Lucid Dream by Owl City before you go to bed

HOW THIS MIGHT WORK: The song (if it's the type of song you like) would put you in a relaxed mood, along with the lyrics, which talk about lucid dreaming and generally "dreamy" stuff that would make you think about lucid dreaming while you go to sleep.

Now remember: this is just a theory. There is no guarantee this works or not but could at least be used along with other methods. Maybe I just like the song a lot.
