Oddly, I thought I was the only one that experienced that Ghostly Vibrating Leg, but apparently Dilbert author Scott Adams has it, too:

Lately I’ve been experiencing a bad case of Phantom BlackBerrry Vibration Syndrome, or PBVS. With this condition I am positive that my BlackBerry is vibrating in my pocket, only to discover that it is my imagination. About ten times per day I feel the vibration and think “Ooh, it’s an e-mail with good news!” So far, the only good news is that my pocket is vibrating, and that’s okay because it gives me hope that the condition might spread to the rest of my pants.

I’ve reached for my cell phone many times, thinking that it was vibrating, only to be left wondering, ‘did I really just imagine that something was vibrating in my pocket?’ I mean, how can you be mistaken about something like that? Either something in your pocket is vibrating, or it isn’t. There is no in-between.

Other things with similar, reality-bending effects include:

• Changing my ringtone leaves me in abject confusion whenever anyone’s phone rings
• Any innocuous ping! sound makes me think, just for an instant, that I have email
• Blue or underlined text, on paper, makes me instinctively poke it with my finger like a hyperlink[^1]

Habit is the hobgoblin of tiny minds – My mind is tiny as they come, therefore my pants are full of hobgoblins.
