Phantom vibrations

Do you ever have your cell phone on vibrate and think that its going off when it isnt? I get it on occassion. I can be somewhere doing something when I feel a vibrating sensation on my hip. I check my phone and theres no calls. I dont know why Im fooled by it because in most cases, the phone is set to ring for incoming calls. That never seems to enter my mind when I reach for it after feeling the sensation.

Its like that phantom sensation that people have reported feeling in their amputated limb. They'll complain about an itch on their finger or toe. But the appendage in question was lost some time back for some reason.

It may happen once in a day but rarely happens any more frequent than that.
