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.

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.

Hourly Pattern

Sleep Paralysis
Another late night and no REM sleep. The hourly view, pictured above, sometimes shows interesting patterns, but I have not yet figured out what – if anything, they mean. 

I have a suspicion, for example, that the first fifteen minutes of relative silence could be due to sleep paralysis. But I was not conscious at the time, so this calls for further investigation.

REM Alarm

REM Alarm
The volume was too loud and the track woke me up right out of the dream. A further contributing factor may be that I have been using the anthem as the ringtone of my phone in the lab as of late. But I feel like I just got home, which confirms other researchers’ findings that a person feels the most refreshed when awoken during the REM phase. 

The 8 blinks required by the algorithm to play the anthem can all be seen in the minute above. The 3 twitches that followed the anthem (after fREM) is a feeble attempt to cling onto the dream and all the noise in the minute after this one is wakefulness.

REM Rebound

REM Rebound Chart
There was too much to code at the end of the night again and I logged off very late. For the third time in a row. On top of that, the first two triggers woke me up immediately – right out of the start of the dreams. It was just as though random thoughts were being blown out of proportion. 

In the minute selected above you will see 13 spikes, roughly every three seconds. These are the blinks or rapid eye movements. The smaller blue spikes in between them are the heartbeat, but it is not very clear in this recording. The orange line (fREM) is when the program played the audio track.

The final REM cycle started with abnormally long / powerful blinks, which luckily slipped past the algorithm. And I had the longest dream on record; 15 minutes of non-stop rapid eye moving action. The anthem triggered at a perfect part in the dream, raining music from the heavens and a few minutes of solid lucidity at the end.

The Free Fall

Falling Asleep - Free Fall
You know that feeling that you get when you are just “falling asleep” and you get startled awake by an intense falling sensation? Well, I was lucky enough to be wearing my halograph after working very late when that happened last night. I was convinced that all of the measurement axes would be spiking much longer, but the effect is barely noticeable in the minute above. 

As a consequence of coding too much and sleeping too little, there is no REM sleep in the entire recording. Only a false positive while falling asleep.
