Yeah, I can understand your point about the research aspect. I posted my results when I purchased that piece of crap Dream Maker(WellnessTools). That stupid thing used facial twitching as a REM dector. To boot it only had a sensor on one side. So here's the kicker, I was having a lucid dream, and I remembered in my sleep I was wearing the mask. I was looking for the lights, listening for the sound and nothing. Least to say I sold the thing on Ebay and got my money back. It didnt work for me but I was having a lucid on my own.

Note: When I first got the thing I put it on and closed my eyes and moved them as much as possible like I was in REM. No detection at all, it seem to trigger when I grinned or smiled or opened my mouth. (facial movements)
