Sleepy Time

I've been worried that I'm not sleeping very well, so over the past year and a half I have sometimes used an app to track my sleeping.

The app is pretty easy to use. I just turn it on, put my iPod face down on the bed next to me, and go to sleep. The app also offers a "soundscape" to help me sleep, which is really just a recording of ocean breezes and waves. I'm sure it's supposed to be soothing, but really it sounds like a toddler splashing in a tub.

Somehow, the app uses my movements on the mattress to record my sleep throughout the night. 

The orange stuff is when I'm awake, the green stuff is light sleep, and the blue stuff is deep sleep. Obviously I can't verify that all of this is correct, 'cause I'm asleep, but the patterns of me waking up do often match what I remember from the night.

There's one more color that shows up: gray.

Gray means there's not enough data to be recorded. The gray used to show up occasionally, as seen above. But more and more lately, it's shown up with more gray than color:

Why is this? Do I sleepwalk? Am I accidentally rolling onto my iPod and pinning it to the mattress? Or is it that my iPod, which was the newest and greatest model when I got it, is now super old and incompetent?

Then I got these results:

Either I cease to exist when I'm asleep, or my iPod really is just too old. So I loaded the newer version of the app onto my iPhone and used that instead. The soundscapes on the new version are better. Also, it records my existence as a corporeal being. Win/win, in my opinion. The only downside is that it made me press my thumb against the phone scanner when I woke up this morning, and I was too tired to understand why.
