Thanks your contributing!

I would love to experiment with external stimuli during REM. However, Nunosi makes me wonder how the deivce works. I was under the impression that when you woke up, you could look at the device, and see your sleep cycles. Assuming the X axis is time, then what is the Y axis? Dominant wave type (Delta, Theta, Alpha, etc.)? Can you advise or post a link?

Thanks!
