"You're sitting at work. Your phone vibrates in your pocket. As you reach for it, you look up... and see your phone, sitting on the table.

You just experienced a phantom vibration."

I have not had this, and hope not too-- sounds creepy.

have this happen often

Me too. I figured it was a feature designed to let you know vibration mode is still on...

Hahaha.

This used to happen to me 5-10x a day, but has gone away almost 100% over the past year or so. It still happens to me about 2x a week. This is a very real thing. It's amazing how your nerves remember and replay stimulations.
