Category: Tracks


After explaining the REM-detection algorithm to a friend over the weekend, I was inspired to shed some light on it by plotting each step in the loop on the graph so that it becomes easier to visualize.

The first printout that I recorded last night, 5 minutes past midnight, shows the strained beats picked up by the halograph FM. The fREM channel can be seen counting up each blink or strained beat that peaks over the top line and then triggers the next track in the playlist after the 8th blink.

13 Strained Heartbeats at 0005

And the second printout, recorded at 0017, shows the same thing happening with the OpenREM channel from the OpenEEG electrodes.

Eye Movement Count from EEG at 0017

This will make it a lot easier to perfect the algorithm by highlighting where it was thinking about triggering. The tracks at 0618 made it into the dream and helped me stave off a hoard of zombies, but didn’t trigger lucidity…

Triggering lucidity
I became aware of the previous song stopping abruptly. Not from the song that started in the minute above. A flurry of eye movements can be seen in the middle of the snapshot with traces of another one of those 30 second waves in the first half.

According to a team of neuroscientists at UW there are:

Neurons in the mammalian brainstem that focus exclusively on new, novel sounds, helping humans ignore ongoing, predictable sounds. The neurons are located under the cortex in a part of the brain called the inferior colliculus. These neurons provide a unique model that can be used in the future to explore some of the neural mechanisms underlying memory, prediction and selective attention.

So instead of just introducing new signals to attain lucidity, it may be worth further investigation to trigger lucidity by removing persistent signals…

REM Sleep After Ninety Minutes
The first audio track played exactly 90 minutes into the session and the movements lasted for the duration of the song. I was expecting the vocals to kick and was disappointed when they didn’t. I will have to cut them in as soon as possible. The second audio track played 65 minutes after that; six blinks can be seen in the minute above before it woke me up.

Sleep and Consciousness Research Graph
First night using the FIELD mouse (and that pun will probably never get old). I had my mouse duct taped to my hand, and I messed around with it for like an hour and a half trying to get it comfortable. Finally I did, and I ended falling asleep around 2:30, forgetting to actually hold down the button.

However upon waking I discovered that I held down the button 3 times for a very long time. Once from 3:04am to 3:45am, after that there was some small movement and then another click just long enough to trigger it again. Next one was from 5:53am to 6:34 (featured), another flurry of movement. And the last one was from 7:09 to 7:25, just before I woke up, the movement was delayed by 30+ seconds this time.

If any of those were from me dreaming, I didn’t experience/remember any of them. It’s quite likely that I was just laying on my hand or something. I also woke with my headset unplugged so the delay in movement on the third “dream” could have been from that. Though just a note, if these were dreams, it would mean that the songs were triggered just after they ended, so it might be a good idea to have a version where the song is triggered after oh 10-20 minutes of holding down the mouse.

I woke up feeling very refreshed for only having had 5 hours of sleep, so I’ll definitely be doing this again, hoping for better results though.

Rapid Eye Movements
The audio track played after a series of more conventional and more rapid eye movements that I will now be focusing on with the help of the new respiratory artifact filter.

Eye Movements Dream
The audio track played after six blinks and the wave can be seen at the end again, as previously noted: 2012-06-14 – Aware-Wave.

Rapid Eye Movement Sleep
The audio tracks played three times during the night but ended the dreams each time. I woke up feeling very refreshed with the third song playing. Well over a dozen rapid eye movements can be seen in the featured minute.

Vibrations Before a Dream
The minute before this one was full of movement. Another ten seconds of the vibrations can be seen here followed by five blinks that caused the audio track to play.

Eye Movement Wave Waking Up
The audio track played after six blinks and woke me up. A wave can be seen at the end that I have noticed a few times before when waking up and remaining perfectly still. I waited patiently for the visions to return to no avail.

Audio Tracks During REM Sleep
Four tracks played within six minutes: two of the tracks can be seen in the featured minute and I distinctly remember when the second one played. The rush from knowing that the world around me was a dream can clearly be seen in the seconds that followed. I tried to control my eye movements for the first time, but the effect I was hoping for did not make it across.

Another track played in the morning and woke me up during REM sleep, feeling very refreshed.

Preparation: chewed a few calea leaves.
