Ok, I set up my laptop for 3:30AM to play a message that was short "dreaming ... Red XIII" so that I would be able to have a goal in the dream, which is to meet that character. When I set it up I made sure the volume was not too low or too high.

Well, it didn't wake me up, which is a good thing, but I don't recall hearing it. I had set another sound to wake me up at 3:40AM. I'm not sure if 10 minutes is too long between implanting the voice and initiating the wake up.

I'm wondering if there is a way to know whether this dream input worked, or maybe how to tell in the future. I've seen other lucid dreaming audios on this site, and was more interested in finding ways to determine their effectiveness. For all I know it may have worked and I just don't remember.
