Not so good vibration

I've recently experienced episode of "phantom vibration."  I've been walking, sitting, riding in my Jeep when I feel a vibration in my pocket or on my hip, reach down to grab the offending device, only to find it's not vibrating.

I'm not exactly sure what to make of this phenomenon.  I've carried a cell phone for years, pagers for years before that.  On my person, at almost all times are three devices capable of an inorganic vibration.  I carry my phone on my belt next to my insulin pump.  My continuous glucose monitoring system is usually in my hip pocket.  Two of these devices routinely vibrate to let me know that my diabetes needs some attention.  My phone rings routinely to let me know that someone else needs attention.

The phantom vibrations tend to happen when I'm at work, between tasks during a busy day.  Most of my days are busy.  On the positive side, the phantom vibration causes me to be mindful of my diabetes and, by extension, my health.  That's not so bad.  On the other hand, it's fairly annoying and, frankly, makes me think I'm a little nuts.  At this point, I've not found a lesson in this weird occurrence--it's just weird and a bit annoying.  Perhaps there will be more on this later...
