Thor used to wheek like crazy when handled when I first got him, it was down to fear with him. He is now used to being handled and quite happy to quietly explore your lap and no longer tries to burrow into you to hide. It just took a few weeks of him getting used to daily contact with people, he still will not take food from and hands but i'm sure he will one day.
Shaking I have not see outside of rumble strutting, Thor did used to HISS (which is extreme fear) around people but not anymore. The most noise I hear which is normal is when I enter the room and they think I might have veggies....super loud whistles and wheeks because they thing they are getting food.
