Well, in the morning whenever my alarm clock goes off (it's a soft melodic ring) dream characters react to it for a few seconds before waking up. For instance, I was in class in a dream and my alarm went off. In the dream, it was the class phone ringing. My teacher went over to it, answered the phone and said something to me. At this point I woke. So I decided to further investigate with that technique using the application, turning music on just loud enough for me to catch but low enough to wake me up. The application works like a charm.

Maybe this is all in my mind actually, placebo if you will. But it is working for me.
