This article talks about phantom vibrations. Here’s an exert:
“If your hipbone is connected to your BlackBerry or your thighbone is connected to your cell phone, those vibrations you’re feeling in the car, in your pajamas, in the shower, may be coming from your headbone.”
This made me laugh. It reminds me of my former friend. We were best friends for nine years and apparently I “grew” on her. Let me explain. I hear best from my left ear so when we chatted we did the sensible thing: she would always walked on my left side. Well imagine doing this for five years or so with the person you spend a lot of your waking hours with. She developed a habit of walking on not only my left side, but everyone’s left side. She felt wrong on their right side. So this habit became ingrained in her – much like the vibrations of a Blackberry may become ingrained in a BB addict.
