Fascinate vibrates when off and charging??

[jrkrace]

I'm really puzzled here.....Every night when I get home, I turn my phone off and stick it in the Samsung dock to charge. Then, while in a deep sleep induced stupor, the phone vibrates for a second. It just does it out of the blue. Doesn't turn on or anything. I went into the hidden menu and unchecked the full battery notification and the phone still vibrates. Am I missing anything?

Thanks in advance...

Yeah mine just did this for the first time the other day...couldn't figure out why.
