Faint REM

Weak Rapid Eye Movement
The REM was too faint again and snuck past the algorithm this time. Around 16 blinks can be seen in the featured minute.

Insomnia

Insomnia
I drank an entire energy drink in the evening. I have not had one in many years and could not sleep as a result. The FM reading, which usually has the heartbeat averaging at around 300, can be seen idling between 600 and 800 in the minute above.

Lucid Dreaming
I experimented with a slightly different position of the sensors in the halograph. Although the eye movements are a lot weaker than normal, they were luckily just strong enough for the algorithm to detect. 12 blinks can be seen in the minute above when the track was almost seamlessly integrated into the dream.

Wake Back To Bed - WBTB
I fell asleep with the halograph idling on the bed post and only put it on when I woke up at 0430. REM started within 7 minutes of lying down again. This demonstrates the effectiveness of the wake-back-to-bed technique. Around 10 erratic eye movements can be seen in the minute above.

Toddler Heartbeat at Rest
My first-born son has been asking for his turn to try the halograph. As a natural lucid dreamer I believe he is more intrugued by the idea of hearing “uncle” Tiesto, his favorite DJ, spin in his dreams than by inducing lucidity. 

I can’t see any distinct rapid eye movements in the recording, but got some good heart rate measurements. A very rough observation from looking at just two minutes; my heart beats at a rate of 50 BPM whereas his heart manages 74 BPM at rest.

Heartbeat

No dreams that I can remember, only a good, clean heartbeat reading; 50 beats can be seen in the minute featured above.

No Rebound

No REM Rebound Chart
After a few nights of too little sleep I was expecting REM rebound again but only recorded a minute.

Dream Alarm

Dream Alarm
There are two blinks that look more like flutters in the minute before this one, which I believe caused the track to play repeatedly. And me to wake up in the middle of a good dream. I removed the halograph and made a note to debug this.

Earthquake

REM Detector
I started dreaming at 0243, became lucid at 0244 (pictured above) and removed the halograph at 0259 at the end of the dream. A very strange wave-like pattern can be seen in the hourly overview starting at 0306 and ending at 0706. This was recorded while idling on the bedpost. An earthquake, perhaps, thousands of miles from the Ring of Fire?

Lucid Dream Measurement
The track played within a minute of the onset of REM and interrupted the blinking for 30 seconds. After stopping to study the minutiae in my hands long enough to be sure, the blinking continued in the next minute during a spurt of lucidity. The brief flight that followed, albeit well under a minute, was worth all the hours that have gone into this over the years.
