Eye Movement Types

Rapid Eye Movement Types
There are two distinct classes of eye movements that I have been observing. There are the solid blinks, five of which can be seen in the first twenty seconds of the minute above, that peak for over a thousand milliseconds. 

Then there are the twitches, six of which can be seen in the second half, that barely last a hundred milliseconds. I suspect that some are lost because the resolution (10 FPS) is too low; there was probably one before and one after the four twitches in the middle.

REM Lucid Dream
I became lucid naturally, the old-fashioned way. So when the track played the euphoria and confidence doubled. But I flew too high too fast and the dream started fading very quickly. 

Three blinks can be seen before the anthem, then some strained eye movements followed by another four blinks.

Heavy Eyes

Weak REM.
I went to bed late; six strained blinks can be seen in the minute above.

REM during a Dream.
The track played within a minute of the onset of REM – after 8 blinks, and the dream lasted for almost 3 minutes, although the effect of the anthem is not noticeable on the eye movements.

REM Wave

Alternating Rapid Eye Movements
I can sometimes see a 30 second wave-like pattern in the intensity of the blinks; two such waves can be seen in the featured minute.

Alternating Rapid Eye Movements
The nine peaks in the minute above are part of seven phases of REM that occured during a ten minute window where the blinking started and stopped roughly every thirty to sixty seconds. The track had played twenty minutes earlier, but I have no memory of it.

REM Pattern

REM Sleep Pattern
Another one slipped by. Now that I finally have the playlist functionality implemented, I need to rework the REM detection algorithm in light of all the dreams I have recorded since I wrote the first version. 

Fourteen very solid blinks can be seen in the minute above taken from a dream that lasted over ten minutes. A lot of the blinks drop below the 800 line inside of the blink, which is what is throwing the algorithm off. This can be seen in blinks 5, 6, 7 and 9.

Short Dream

Graph of REM Sleep
Eleven rapid eye movements can be seen here in a dream that lasted for just under two minutes.

Calea

REM Sleep with Calea Zacatechichi
Around six rapid eye movements can be seen after the vibrations. This is one of only two 30-second REM phases recorded during the night. 

Preparation: added boiling water to a cup with a teaspoon of Calea leaves and let it soak until cool.

I have had great success with the tea inducing long, vivid and lucid dreams in the past, so I will have to try again soon.

REM Sleep with Mugwort
The track interrupted the rapid eye movements after which the dream continued for another two minutes, although I have no memory of it. 

Preparation: boiled two tablespoons of Mugwort in two cups of water for 10 minutes until half a cup was left.
