Interesting. I looked into this product when I was searching on this subject.

My goal is to use Morse Code as a dreamsign since the common flaw on all lucid masks is that the random flashing of lights are easily interpreted to be something familiar such as police lights or someone flicking a lighter on and off in front of you. I hypothesize that seeing a pattern that your mind instinctively recognize as Morse Code for the word "lucid" that the message will be less likely to fade into part of the dream world unnoticed.

Perhaps if the audio track plaid when REM is detected is the Morse Code it may have the same effect as the flashing would. A combination of both would be most ideal.
