EEG of Hypnagogic Jerk at 0101

I caught that feeling you get when you are startled awake by an intense falling sensation on file again, this time with EEG. At 0052 I was still awake and making sure the audio tracks were triggering, then at 0101 I twitched awake and checked the time.

The minute above shows the episode – the first spike was the twitch and seems to have flat-lined the channel for a few seconds. The rest of the movements are from me checking the time and settling again.

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.
