What do you mean by saying that you're using a mask path to move a layer? If you copied and pasted the mask into the layer's position, there are multiple ways to vibrate it.

One that springs instantly to mind is to add the wiggle expression to the position.

Another suggestion would be to keyframe (or apply wiggle to) the anchor point.

yes you're right i copied a nd pasted it.how can i add a wiggle expression when you have position keyframes???

The same way you add a wiggle without position keyframes.

Alt-click (PC) or Option-click (MAC) on the stopwatch and type your wiggle expression.
