Sound Induced LD

I think it came up before, but what would happen if one were to listen to himself saying “You are dreaming” (Using an mp3, ofcourse)

oh it is a good idea that at night to send an mp3 to signal at a time when your definetly asleep at night, that it would say something like that, since you would be able to hear it

So, you could just use your laptop or mp3 or w/e and dl audacity to make your mp3
