Paper moving in a slight breeze effect

Hi

I'm trying to create this effect but no luck so far:

The paper is not attached to a book or anything. It's a simple rectangle with a shadow.
The bottom right edge is slightly upturned and has a shadow underneath to give the effect that the corner is slightly folded. We are looking at it from the top view as if the paper is on the floor.

I need the paper to slightly flutter every few seconds as if a sudden small breeze just occurred. When the flutter is over, the paper can return to it's original rest position.

If it makes it any easier, imagine the top of the paper is being held down by a pushpin or a thumbtack. So all that would happen is the bottom slightly lifting and swaying left/right then stopping.

Can anyone show me any examples or give me some tips.
