Great news!

With some tweaking, my next sleep session had much crisper rem-period detections -- enough that it correctly identified both of the dream periods (which I marked with a hand gesture after awakening from them), without any false positives.

Granted, the sleep session was not a full night (it was only about three hours), but I'm still very pleased with the results, and am confident in its long-term usability.

Below is the raw log of all "eye movement detection" moments during my sleep, where the "eeg activity" (ie. clustering of eye-movement detections around that point) is above the minimum to be considered a period of dreaming (5). (the "peak" value shows how much movement there is within that particular eye-movement 4s detection period)

==========
The two lines where it shows " << ..." after it are the markers of the two times where I woke up from a dream, and did a hand motion that was recorded by the camera.

This matches up well with the two sequences of eye-movements, from during the two dreams. (followed by a short while where I shift around)

(Oh, and the two sections at the start and end are of course from moving around at session start and end.)

Anyway, I'm very pleased. I'll tweak it a bit more, but then I move onto phase 2, which is finding the appropriate prompts which are able to wake me -- just enough that I awake, and then stop moving my eyes, which will deactivate the prompts and allow me to attempt a dream-reentry. I already have light and shake prompts set up (which activated fine), but I need to fine-tune the activation points, as well as train myself to be able to wake from them without breaking my dream-like immersion too much.

Regarding display of nights' data, the program will soon have nice graphs and such showing the periods of rem, markers for awakening, etc. The text-log format above is just being used until I finish the user-interface + image/video capturing for that.

While I haven't gotten a lucid dream from the system yet, I did have two vivid dreams in the above session (as signaled at the two marked moments). And more importantly, the rem-detection system seems to finally be functioning, which is great to finally have available.

Onto the prompt-configuring, and mindset-training phase now!
