Phone keeps vibrating randomly

This has never happened before but the past couple of days my phone will randomly do a short vibrate. No idea what it is from, no notifications present.

Ah ok, mine will do a short vibration if there is a message on it. Also, if i pick it up and touch some part of the screen, the device thinks I tried to unlock it and does that to tell me that I got the password wrong....
