Phantom Vibrations

I have a buddy who claims that he gets phantom vibrations because of the vibrate function on his mobile phone. After months of using this feature, he says that he feels phone vibrations on his body when he doesn't even have his phone with him at all. First of all, vibrating phones freak me out. My phone has the ability to vibrate, but i don't ever use it ever. Ever. It's like a time bomb in your pocket. And I'm not down with having this vibrating thing in my pocket going off whenever it feels like. I don't like it. It feels naughtier than that time we stole into Old Man Wilson's garden and ate all his turnips.
