Thread: Muse S headband (for REM-detection in custom LD-induction app)

Another night session:


Note that, like the previous session, there is one cycle at the start with a lot of rem/eye-movements, but not much in the cycles after that. (and this matches with my memory, of a semi-lucid dream [noticing malleability, but not as dream specifically] at the start of the night, followed by "not much" after that)

I believe the cause of this (both this session and the previous) is that when I went to bed, I was pretty tired/sleep-deprived. So it seems that, when I'm sleep-deprived, the "rem rebound" that occurs is focused at the start of sleep (at least the last few times). This is interesting, as I had assumed previously that rem-rebound would merely increase the rem intensities a bit throughout the night. Instead, it seems to cause a "super rem cycle" at the start, followed by a series of rem segments that are actually less intense than normal. Of course, I can't confirm this from just a couple nights, but we'll see if the pattern holds up.

It's so cool to be learning things like the above, by examining the raw data each night. (I think it would be harder to do this with sleep categorizers that only say what stage of sleep, rather than showing the raw eye-movements chart -- as this lets me see differences in intensity, not just duration. I did not realize previously that the intensity of rem varied so much from cycle to cycle.)
