OpenEEG recording of a lucid dream
I had a rare natural lucid dream triggered by events inspired by the main theme of Bob DeNatale’s new film about lucid dreaming, The Art of Dreaming. I maintained lucidity for a good minute of human flight. The minute featured above shows a spike in the data that is otherwise flat, recorded at 0614, when I believe the dream occured. I was asleep from 0015 to 0640.

The algorithm didn’t trigger an audio track, as it was looking for multiple events like this in a row. I will update it to optionally trigger on only a single event, because of the vividness of the dream. The spike looks similar to when I open my eyes while awake.

Sleep and Consciousness Research Graph
I have make a Remote Viewing Session (german: Fernwahrnehmung) and have recorded my brain with my mindwave headset from neurosky.
The Session is from Stage 1 to 6 , and by the way.. its a Coordinate Remote Viewing Session (CRV).

EEG Baseline
The minute above shows the “normal” EEG values when I am still. I can move my head around quite a lot without affecting the values. But as soon as I move or close my eyes, significant peaks can be seen like in the minute below that I recorded during my sleep at 0825.
EEG Eye Movements

I woke up at 0841 right out of a dream.

OpenEEG Project - REM Sleep
A decade after I was able to afford my first printed circuit board from Olimex and started dabbling in the OpenEEG project, I finally managed to build a device with which I can comfortably record my brainwaves during sleep.

It took forever to fall asleep because I was just too excited. I woke up at 0534 from a dream and noted the time. The printout of the minute I selected is from 0515 and shows some very distinct patterns that are similar to when I move my eyes around while conscious. I will use that as a base to write the REM-detection algorithm that will trigger the audio tracks.

I embedded the four active electrodes inside a headband and taped the passive electrode to my earlobe with some duct tape. I still need to meditate on a more convenient way to attach the passive electrode.

It can be worn with the sensors on the forehead by the Frontal Lobe to trigger on the spikes in electrical activity caused by eye movements or at the back to monitor the brainwaves by the Occipital Lobe where visual perception is processed. Check it:
Halograph EEG

Anyone with a device compatible with the OpenEEG project can now upload to the Lucid Scribe Database project by right-clicking on a log in Lucid Scribe and selecting Export to -> LSDBase. The source code for the OpenEEG plugin is available on GitHub.

First Dream with Modified MindWave
First dream captured with modified NeuroSky MindWave. Anyone familiar with the MindWave knows its design makes sleeping with it on nearly impossible. I took mine apart and remounted the boards, contacts and battery (crudely) in a elastic headband. Now it is possible to sleep with it on.

UPDATE:
Thought I’d do the process in bullet form. To be used in conjunction with the attached pics. Unfortunately I didn’t take step by step pics but it is really pretty simple. If I forgot anything feel free to ask.

  • Remove all the stickers from the mind wave including the large circular one that says NeuroSky MindWave. They just peel off.
  • Unscrew everything
  • The blue wires Going to the forehead sensor can be carefully pried out of the sides.
  • Gently remove the boards and refer to pics for wiring scheme. These wires/connections are fragile!
  • Buy a battery holder or cut away the original one and add wires to be able to mount it in a more comfortable position.
  • Adapt or replace the forehead sensor
  • Mount into headband as suits your needs.
  • Sleep, Dream, Be Amazed

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.

REM Sleep Graph
The respiratory artifact filter has been ignoring too many events that could have had potential, so I have some more tweaking to do. In the minute above there are over two dozen movements that failed to trigger the audio track.

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 Movements Electroencephalograph
After a few nights of recording brainwaves from the NeuroSky MindWave and some advice from a cognitive scientist, I was able to write an algorithm to detect REM sleep from the raw EEG data.

Thirteen blinks can be seen in the minute featured above. They look uncannily similar to the rapid eye movements previously recorded with the halograph FM. The audio track was triggered five times throughout the night and interrupted REM sleep at least once.

Also of interest is that the attention graph tends to spike during REM sleep, when the meditation graph tends to trough.
