The other day after waking up with a song stuck in my head, I realized the song that was stuck in my head (which I remember recognizing in my dream) was also playing when I woke up.
Obviously this wasn't a co-incidence - It's possible to listen to music whilst being asleep.

Well, Ok... thats nothing new. But the idea hit me:
If we're able to consciously listen to music in a dream, then why don't I create a song with the main lyrics being something like ''remember that your dreaming'' or ''make a reality-check'' (in-fact it could be just words without music) and then set it to play early in the morning.

If everything works as planned, assuming that the music starts to play while I'm dreaming, I should hear the lyrics and then question if I'm dreaming. Thus causing lucidity!

So what do you think? Have any comments or suggestions?
