So i was reading some random posts about bineural beats and i noticed that lots of people still hear the music in their ears when they are dreaming, that gave me an idea.

Basically record yourself saying "do a reality check" or "Am i dreaming?" or something along those lines. Put it on an mp3 player so it repeats then listen to it as you fall asleep.
It seems you are more likely to hear it if the volume is more-than-quiet.

Technically if im right you would hear that in your dream and (hopefully) it would make you aware of your state.

Anyways tell me what you think or if somebody has already suggested this.

Feel free to try it and post the results here because i most likely wont have time to do it myself for a few days.
