S60 Electrics: My Car is possessed?

[S60-MBS]

Sat in shopping centre car park yesterday evening waiting for the better half to return, had my engine running.Noticed that my driverside mirror was slightly out, I adjusted it using the controls on my door,the mirror controls have to activated by the power buttons before adjustment which I did and then switched back off ,both lights on mirror control panel were off.While sitting there gazing into thin air I heard a tiny buzzing sound and looked around and saw that both my mirrors were adjusting themselves up & down,left & right at exactly the same time.Immediatly switched the car off and the mirrors also stopped roughly at same time.turned car back on and adjusted mirrors back to what they where supposed to be .Its been over 15 hrs now and nothing further has happened.
Is this one of the control modules playing or something more sinister?

Its doing it again at the office car park, this time there is a clicking sound from under the steering wheel area. Think I will leave battery off for a while.Wish I had a video cam with me for this.

It did happen to me before once or twice, when I was trying to park my car and wanted to see how far I was from the kerb, both mirror moved at the same time funny and strange.
